See what our clients have to say about Big K Computers:

I would be remiss if I did not take this opportunity to write a comment regarding Kevin and Big K Mobile Computing. On a call for assistance, Kevin promptly and courteously returned my call, and scheduled a convenient appointment. Kevin exhibited exceptional professional and people skills at a reasonable cost. His recommendations were all well thought out and his exemplary technical skills resolved my concerns. Kevin has returned my calls and answered my additional unrelated questions without further charges. Highly recommended for your computer needs.

Big K Mobile Computer Services is my go to for purchasing computers or any computer related issues. Kevin is an all around great guy. Professional, dependable, personable, reasonable AND he can work and talk at the same time! TicToc. When my work computer goes south on me, I send an SOS to Kevin and when he walks through the door my anxiety level goes back to normal, because I know my computer is in good hands and that the issue will be addressed quickly. Big K performs regular maintenance on my work and personal computers, so that really cuts down on issues and fire drills. No better computer than one that doesn’t fight back 🙂 I found Big K years ago through a referral and I couldn’t be more pleased. You will be too!

Ken is a consummate pro; completely knowledgeable, friendly, on-time, and totally helpful. Not only did he do a wonderful job with the installation, he offered suggestions as to how I could further boost my laptop’s performance. I highly recommend Ken to any serious user. FIVE STAR GUY!!

Kate Nashua, NH

Kevin at Big K Computers was recommended to me by a friend and it is the best recommendation that I have received. Kevin is extremely knowledgeable in the tech world, friendly and takes the time to explain whatever your needs are in a way that is easy to understand. He also guarantees his work for 30 days. So if the problem continues, he will come back out and take care of it. The last time he came out, I had a problem with my computer — he helped me with that. Then he helped me with my cell phone. Then he helped me with my new smart TV. He knows it all. I have his number programed on my phone so I can reach him quickly, if I need to. You won’t be sorry if you call Kevin Harms.

I want to first start off by letting everyone know how awesome Kevin is as a computer tech. I found him probably around 4 years ago, when my one of my computers at my business was giving me problems. He is so efficient on how he handles his arrival times, its so refreshing to deal with someone who does exactly what they say they will do. He is really upbeat and funny while always working and getting the job done quickly. He even will let you call him on a small problem that he thinks he can walk you through at no charge. I totally recommend Kevin to anyone needing mobile computer service at a fair price. Thanks Kevin.

Penny Batelli Tucson, AZ

Terrific person and service. Thoughtful advice, helpful explanations, prompt, generous with his time, goes out of his way to come to our house when needed.

Steven V. Lexington, MA

A friend recommended Kevin to us and we in turn recommended him to other friends for many reasons. He is very conscientious in returning voice mail and email messages, makes every effort to schedule a convenient appointment time (How much easier is it to have him come to your residence or business instead of carrying your computer somewhere?), is very prompt, personable and professional. We appreciate his patience in working with our 14-year-old grandson and with us 75-year-old grandparents. His people skills and his ability to explain and teach are awesome! He goes out of his way to assist in any way he can.

Roger Duthoy Yorba Linda, CA

I’m one of those senior citizens that doesn’t know a great deal about the workings of a computer but Kevin is very understanding of any problems that I have. He patiently explains any concerns that I have. I like that he answers emails promptly and never seems to be rushing me. He is just all-around pleasant and knowledgeable.

Lois Heidner Buena Park, CA

I wish there were 6 stars as Ken is an amazing computer technician. Professional, courteous,
knowledgeable, and very efficient. The best recommendation I can give is that I tell everyone e.g. family and friends that they no longer have to be stressed out over technology. Ken is a phone call away and fixes all dilemmas right away. He set up my computer, printer, LCD projector, phone and also gives tutorials!!! The BEST service I have ever encountered.

E G. Bedford, MA

I was recommended to Big K Mobile by my neighbor. I called Kevin up and he came over in a day or so. When I opened my front door Kevin greeted me with a big smile,was very friendly and courteous. We proceeded to my office and within 25 feet of my pc he said your computer does not have any mechanical problems. I said how can you tell so fast and he told me over time that he has acquired an hear for sounds in a pc, That really impressed me. Kevin was able to take my computer away and bring it back in 2 days, completely overhauled, and running great WOW! Since then I’ve called Kevin on several occasions and he has been able to answer my questions and has not charged me extra. Kevin goes above and beyond for his business which shows me his dedication to his profession. We will continue to use Kevin and also to refer Big K Mobile to our friends.

Wayne Zie Buena Park, CA

I am convinced that Mr. Kevin Harms and his Big K Mobile Computer Services company are both as good as it gets when I have needed computer services during these last 8 years that we have used his services in my dental office. We have 8 computer stations all interconnecting and of course issues come up unexpectedly.

We call Kevin. He communicates back right away. Whether it has been an emergency bug infection, or a computer needs replacement, or even the server needed totally upgrading, he appears as promised, always with a positive attitude, Kevin has done it very smoothly every time! He is a very well informed technician at computer structure. He is also a whiz at working with Microsoft Office and QuickBooks to make our computing such a headache-free routine in our office!

May you continue to prosper in your wonderful company!!
