Many clients of TwinBytes have taken the time to let us know how much they appreciate our help. Here are a few letters from satisfied clients of TwinBytes. Some reviews and testimonials were sent by email, others posted on Google, Facebook, etc.
“Twinbytes has been a lifesaver for my firm. The monthly monitoring, virus protection and full-copy backups have saved us on several occasions. Most recently, we purchased brand-named refurbished computers from a highly reputable national distributor. One-by-one, the drives on these computers began to fail. We were so fortunate that the failures were caught by Twinbytes through the 24/7 monitoring which allowed us to replace the failing drives utilizing the real-time back ups before we suffered catastrophic loss. Additionally, having the failures captured in the monitoring records, allowed us to easily resolve matters with the supplier on an amicable and thoughtful basis. The expertise, advice and positive support offered by Twinbytes is crazy good and it expands with our needs and the changes in the world of IT. So lucky I met Daniel so many years ago; hard to believe it has been over 20 years. He is a highly valued professional partner in our firm’s operations. I do not know what we would have done all these years without him. And I am thankful for this opportunity to share our appreciation for all that Daniel has done for us, with this post. And just to be clear, it is not just about the service….it is about knowing that you have a reliable “go-to” for IT advice and guidance when you need it!”

Daniel at TwinBytes was an absolute lifesaver! After my daughter accidentally knocked her laptop onto the floor and completely shattered the screen, I thought we’d have to replace the entire device. Thankfully, Daniel was able to repair it quickly and replace the screen at a fraction of the cost of a new laptop. His expertise, professionalism, and honesty truly stood out. I’m so grateful for his help and highly recommend TwinBytes to anyone needing reliable and trustworthy tech support!

April 3, 2017 I recently had a problem with Microsoft Office. I spent 5 days on the phone dealing with the representatives at Microsoft Office 365. They sent me from department to department with no resolution. I brought the issue to Daniel. He was able to resolve the issue within an hour, and my Microsoft Office is working properly. Daniel was very accessible, friendly and helpful. I look forward to continuing to work with Daniel.

November 29, 2016 Daniel Gauthier of TwinBytes is no ordinary human being. I met Daniel at MACC (Markham Association of Community Champions) where he shared his passion and love of giving back to the community. I run a social justice group for kids here in Markham www.thegivingtreeunionville.ca and at our last meeting made a shout out for inspirational speakers to come in and share their life experiences with my youth. Daniel jumped at the chance and within 72 hours, had prepared a presentation on Stereotyping and bullying. He came roaring up on his bike dressed in his full biker gear and made a huge impression. He presented and spoke in great length about the consequences of stereotyping individuals and bullying and how we can be positive change makers. Daniel, thank you so much for your time and for sharing your experiences with us. We look forward to welcoming you back again in the New Year!

I highly recommend Daniel at TwinBytes for any computer assistance! After my hard-drive failed and showed up empty on a hard-drive reader, I was told by several other companies that it was un-repairable and would need to be taken to a clean room to retrieve any data (if I was lucky). I had very important data on my hard-drive and Daniel was able to retrieve 90% at a fraction of the price compared to what I was quoted elsewhere. The turn-around time was also a lot faster, and I was back up and running within a few days! Daniel was very attentive and professional and I will be using TwinBytes moving forward for any computer related assistance. Thank you Daniel!

TwinBytes Inc. not only the best computer repair in Markham but also has performed a miracle for me. My computer crashed a few years ago. I went to another computer repair company, they repaired my computer but told me that a few files was deleted and lost not able to retrieve. That was a very shocking news for me I had just lost months worth of work. As I was in the shocking stage I remembered of having met Daniel in the past. I called him and took the computer over and that was when the miracle happened. He retrieved all of my files and showed me how to backup for that to not happen again. YES! TwinBytes Inc. for me is one of the best computer repairs.

I found TwinBytes on Homestars and called the phone number on Saturday evening figuring that I would leave a voicemail ffor someone to call me back on Monday. To my surprise the owner, Daniel Gauthier, actually answered the phone himself! He was kind and courteous as he listened to my computer issues. Within 24 hours I had dropped off the computer desktop, had it professionally repaired and picked up without losing even one minute of valuable time. I am so happy to now be a TwinBytes client!!! Great work and extraordinary service!!!Sam Gonshort

Hey there good readers. Do ya have a computer that needs service or want a new one put together right? Don’t bother with Barf-Buy or other computer no-nothings (generally speaking, of course). Daniel Gauthier is a super, knowledgeable guy (and author!) who knows PC’s and PC parts like no one else around Markham. I know what I’m talking about because I am a computer geek and can do a lot of what Daniel can do, just not as well, to be frank. That’s why you pay for what you get in this world. If you want excellent service, affordable solutions to your computer issues and a system that rocks, see Daniel and walk away happy and know you’re in good hands should you need his help down the road. My good friends A & S also had a computer done up by Daniel and are beyond impressed. TwinBytes – thanks for everything so far.

I recently took my laptop, which was not booting and was also running very slowly, to TwinBytes for an assessment. Daniel understood that I needed the computer for business and responded very quickly. He was able to look at the problem the same day, and begin a cleanup that addressed the problems. When I asked for advice on new computers because of the slow performance, he went beyond the initial issues and recommended installing a solid state drive in lieu of purchasing a new machine. As a result I now have a much faster machine, and didn’t have to spend money on a new computer.
Daniel is also very prompt to answer emails when I have questions, and to provide remote support when that is necessary.
Daniel and TwinBytes have helped me for a number of years, and I am very pleased with their support.

Hi Daniel

This machine truly empowers my ability to produce. But it isn’t the machine alone that completes the picture. Your ongoing monthly support and online accessibility guarantees no down time. Twinbytes, the only way to go.Thank you

If anyone needs a computer fixed (home or business) I would highly recommend the place I used recently…TwinBytes Inc. in Markham. The owner, Daniel Gauthier, was fantastic. My home PC was completely dead, it was dying slowly and then took it’s last breath. I was inconsolable…I found Daniel on the internet and brought him my tower that morning and he was able to get it cleaned up, up and running, within a day at less than what he had originally quoted me for. He did not do anything I did not need and he took time to fix my “older model”, rather than just throw in a more expensive new hard drive…I literally would not have known what exactly it needed as this is NOT my area of expertise. He kept me up to date on the progress and I had it back pretty much the next day. he was a super nice guy and a real businessman that cared about my outcome and finances. I would highly recommend him and his services.

Being a small business owner – technology is a very important tool towards my success. I’m sure you can all appreciate what it would be like to experience 2 hard drive crashes on the same laptop. Finding someone to trust to fix it wasn’t easy…but I was lucky and met Daniel from TwinBytes. Not only was it convenient to have someone local working on it…Daniel went above and beyond to get my laptop back up and running. He was a pleasure to work with. I highly recommend my “techie guy”, Daniel, for all your computer issues!

Daniel is a joy to work with. I noticed his calm and can-do demeanour years ago when my hard drive took a nose-dive. And when I came back with the exact same problem recently I was amazed that not only did he remember the hard drive but went the extra mile to ensure that I would have it back as soon as possible.

As a design and manufacturing company of interconnect products for the data communications industry, we rely heavily on our networking system. When it came time to upgrade our server we had to make sure we found a reliable and competent computer services company.
After trying a few companies that created more problems than solutions, we decided to try TwinBytes. I met with Daniel and he developed a strategy to install our new server and upgrade our client workstations.
Well I must admit that I expected some major hiccups but TwinBytes upgraded us seamlessly and virtually transparent to our users. We now have a faster more efficient system thanks to TwinBytes.
I received many compliments from staff as to Daniel’s patience and professionalism and I can personally attest to his ability to turn complex problems into simple solutions. Now that we have our upgraded network in place, we can focus more on customer relations by adding many new enhancements.
Moving forward, TwinBytes will be our computer services company of choice.

I had my laptop fixed recently by Daniel and it was one of the best service experience I’ve ever had. Everything was seamless starting from the initial phone call, taking my notebook into his office, and the repair turn around time. I never felt at any point that he was trying to get more money out of my pocket. In fact, I feel guilty for not paying more due to the urgent nature of my request. His friendly attitude, honesty and professionalism is quite refreshing because it is hard to find these qualities in service professionals these days. I highly recommend TwinBytes to anyone needing computer repair and/or maintenance. He’s also got his own book that I just started reading.. so far I find it very informative and I think you will too!

Our computer hard drive crashed all of a sudden and we needed to have important data recovered. Called several places and everyone just told us to bring it in for a set lab fee.
Daniel from TwinBytes was the only one who asked details on what the drive sounded like, what the screen was, etc.. He said he can try to recover the disk manually first to save some money as it might not be necessary to send it to the lab.
Despite exhausting all his methods, the hard drive was completely shot. He had to finally send it in to a lab to recover the data, but kept true to his estimate on what the fees would be so there were no surprises. The data was recovered and it was still cheaper then all the other phone quotes that we received. He could have easily taken advantage of our situation, but didn’t. Instead he tried to work with us in a timely and efficient manner.
I would not hesitate to use Daniel from TwinBytes again for any computer related problems. Truly an honest individual and highly recommended!

We had some major network issues and not only were you able to fix them but you got it done quicker than I thought possible. Now we’re secure and all of our computers are doing what they’re supposed to do!
In addition, when I called you in a panic because my lap top crashed you walked me through the process, were able to recover all my data and got me up and going quickly. All for a VERY reasonable price. I’ve heard some nightmare stories of people being held hostage to get their data back and have been extremely impressed with your professionalism and value.

I can’t believe it! I took my computer to a place a while ago because the sound wasn’t working. They said it was something with some part that was too big of a job and not worth fixing. They couldn’t do anything with it and said I should either toss it or live with it. I took it to Daniel at Twinbytes and he fixed it quickly for only $35. Apparently it was a simple fix and was incorrectly diagnosed by the other guys.

Thank you so much for your amazing recovery of my external hard drive. I seriously felt like I had been “erased”! You recovered it not only at a quicker speed and more reasonable cost than what others have quoted, you also recovered it AND fixed my corrupted hard drive. I am so grateful for your help. You are so courteous and humble. I knew I could rely on you right away when you called within an hour after I gave you my damaged drive at the end of Saturday, and had all 120GB of my drive recovered on Monday morning. This proves to me you are hardworking, and that you really put a great deal of importance in your clients need. Always, you are so willing to help, either on an individual basis with computer problems, or the whole community with sponsoring sports teams. I can tell you have a heart of gold, and you will always help as much as you can in your maximum capacity. I highly recommend Daniel and TwinBytes!!

I just wanted to express my appreciation to you for fixing and setting up my high speed wireless connections. I have heard only good things about you through other members of the Markham Board of Trade. I’m happy to be able to confirm those reports. You were on time. I left you to go to another meeting. You continued until you were finished, the setup was complete and working. Your rates are very reasonable. You are very polite and professional.

In the past I have dealt with several other computer consultants to maintain our system. None of them have been as responsible as you have proven to be over the past year to solve problems quickly, at a reasonable cost.You described problems in a simple articulate way that the layman can understand.This has not been the case with others we have dealt with in the past.Having had trouble with my own computer recently in Central Ontario, I choose to make a 3-hour trip to your office rather than take another chance on the uncertainty of dealing with a local computer technician whom I don’t know.I wish you success with your business and will not hesitate to recommend you to others when they need assistance.James Lumbers,

Hello Daniel,
In today’s business world with so many ongoing disputes it’s a pleasure to be writing this short note.Petra, our developmentally disabled daughter, always expressed an interest in being able to use computers, for much more than ‘gaming’, but being able to understand and use a computer to the same extent as others of her generation. Using standard software, to design, express herself in words, and communicate with friends and relatives via email. We brought you on board ~ TwinBytes ~ and you devised a program that Petra was readily able to understand. You are to be congratulated, the project you devised for Petra was more than a straight forward learning experience. You resolved many of the complicated technical aspects in a fun way, without any stress to the participant, because of this Petra has an ongoing interest, and is now an avid computer user.Both Viki and myself wish you every success in your future endeavours.Again congratulations on helping Petra along the road to self sufficiency.
