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

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!

Debra Munson Pamela M Smith Security Seminars Inc. Whittier, CA

Kevin came highly recommended to me over 5 years ago by another firm and he is simply terrific. I work from home, on several computers, with multiple operating systems and have exceptionally high document volume and trust Kevin 1,000% to keep everything running smoothly. And when I have a technical issue (usually operator error) or need any kind of computer related assistance, Kevin has always provided tremendous customer service! It is also important Kevin gets right down to business when he arrives – you get more than you pay for! You will not be disappointed!

Kathleen Kennedy Lake Forest, 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

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!!

PJ C. Nashua, NH

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

We have been using Kevin for over 10 years. He is the best most knowledgeable computer tech we have ever had. We have never had a problem he couldn’t fix. He always returns phone calls promptly. He fixes our computers and if necessary orders new ones and sets them up for us. I have recommended him to at least 10 friends who thank me every time that they use him. I recommend him highly.

Doris Fults Buena Park, CA

I have had Kevin and Big K service all of my Tech needs for over 15 years. This includes home and business. I have found him to not only be knowledgeable about anything Tech, but fair and personable too. He is now our family computer “go to” guy too as my four daughters and son-in-laws set up their home and business tech smart homes too. I have been recommending him for years to family and friends and I have always had only “thank you so much for recommending Kevin and Big K”. I have always felt that satisfied customer referrals are a mark of a great company.

Service has always been prompt, excellent and reasonable. As a satisfied customer, I strongly recommend Big K Mobile Computer Services.

Larry Eggeman Anaheim, CA

Kevin is the best! The first time I called him my computer was a mess! He not only diagnosed and fixed that he made a few other changes that improved the functionality and did it quickly. I have used him a few times now and have been very satisfied and found his rates to be very reasonable. He is also responsive and arrives on time which can’t be said about all device providers.

Amy Curtis Laguna Niguel, CA

I have been working with Kevin Harms for three of the six years I have had my MAC computer. Before I was referred to Kevin, who is not even in the same state as I am, I had used many local people. None of these people really were helpful. With Kevin, I e mail him, we set up a phone appointment, he gets in on team viewer and does what I need and he is always reasonable with his charges. I have recommended him when someone needs a MAC guy because I do not think there is any one better!

Marilyn Day Tucson, AZ

Kevin is a master mind when it comes to computers and any wiring services for cable, phone, etc. I have known him for 10 yrs. or more. He always shows up when he promises. No problem or challenge goes unsolved. He works quickly so you really get your money’s worth, and is always fair with his billing. He usually gives you an idea of how long a project should take so there’s no surprise at the end. He walks you through each step of the way to make sure you know how to get back up and running once he leaves. Whether you are setting up a new computer, monitor, or printer, have some odd error message, need to transfer data or set up new programs, set up a network, connect a second printer to fax or scan, or even experience a major crash, Kevin should be first on your list to call. He also will help set up an efficient and best value means of virus protection or data backup. I highly recommend Big K mobile for all your personal or business needs.

Larry Kleiman Larry Kleiman and Associates Los Alamitos, CA

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

Kevin was recommended to me when my son’s computer was acting up. Kevin came out the next day after I called him, looked at the computer, said the computer probably had a couple of viruses and that the anti-virus software that was running was not all that powerful. He took the computer back to his shop spent a couple of days getting rid of the viruses, spiffing up windows, and making sure everything was up to par with the hardware and software. When he brought the computer back, he made that it was working properly, and then he did a run through on my computer to make sure it was working properly. Kevin also recommended a very highly rated and powerful anti-virus software, which we bought for both computers and have not regretted it purchasing it. It actually sped up my computer’s performance.

Needless to say I am very impressed with Kevin. I have used him often, and he even built me a computer that is still faster than most computers on the market today. Kevin is very responsive, answering emails and phone calls either the same day, or the next day when it’s after hours. Also he can explain what he is doing, or what is going on with the computer, to my “computer challenged” wife, so she can be home when I can’t be there.

I highly recommend Kevin! If you are having computer troubles, please give him a call.
