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

My MAC needed cleanup, updating, and stuff I didn’t even know I needed. My guru for the past 20 years was no longer available and Ken was the answer to my prayers. He is knowledgeable, prompt, courteous, and a MAC expert. He fixed problems I knew about and, more importantly, fixed what I didn’t know to ask about. Ken explained what he was doing so that I could understand. He responded promptly to questions I’ve had after his appointment. Ken is on my primary go-to list.

Sylvia S. Dedham, MA

Totally knowledgeable of all software and hardware, Mac and PC. Big K has always solved my computer issues efficiently and at reasonable cost. Very reliable. There have been times when Kevin, the owner, has talked me thru a problem over the phone at no cost. Highly recommend.

Tom Griffthe Anaheim, CA

Kevin at Big K is the best. In ten years of service, he’s always quick to respond, friendly and trustworthy.  When he leaves, I know my computer’s fixed with no issues.

Tanya Hazelton Yorba Linda, CA

For over ten years Kevin has been my “go to” guy in taking care of any of my computer problems. He has fixed the problems when needed and set up new computers when needed. I have found him to be reliable, knowledgeable, always on time and always just a telephone call away for help.
I feel so fortunate to have someone that I can call on over the years instead of having to rely on strangers from problem to problem, never the same person twice.
I do strongly recommend Kevin and I have done so many times and each time he has not let them or me down.

Barbara Morrisey Fullerton, CA

Kevin in the past two years has been very helpful to me in resolving numerous hardware and software issues on my PC and printing device. He gives his customer good response time and is on time for his appointments. He is effective in diagnosing problems therefore doesn’t waste customer’s time.. He also offers warranty period.
For those reasons, I choose Kevin among other vendors to service my PC and accessories.

Susan Lin La Habra, CA

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.

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

I stumbled upon Kevin many years ago when our office needed an expert for our computer systems. From the start, he was reliable, accessible, knowledgeable, professional and personable. We always looked forward to working with him. He was always so patient and kind. I have also employed him to work on my home computers. He is trustworthy, honest and responsible. I don’t know what I would do without him! He is a very special person. I highly recommend him!

Donna Metcalfe Vice President, Teamsters Union Local 952 Orange, CA

Over the past few weeks I have been having problems with certain apps crashing on my computer for no reason whatsoever. I had several different services look into fixing my computer but each had no success. I was reffered to Ken from a friend and I am extremely happy with his service. He went the extra mile that no other company did, and fixed every issue I had with my computer. He was extremely friendly throughout the process and explained everything in detail so that I knew exactly what he fixed. I know down the road if I ever have problems with my computer, Big K Mobile Computer Services will be my first call.

Anthony Gallo

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.

Robert Phelps Huntington Beach, CA

Kevin at Big K Mobile Computer Services is AMAZING!!! I highly recommend Kevin. He is always available when we need him. Very professional, on time, honest and his rates are fair. I will continue to use Big K Mobile Computers in the future.

Tamara Baker 20th Century Air Anaheim, CA

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

I don’t know where I’d be without Kevin.  He sets up and solves all my computer and printer problems, plus he set up my new televisions and netflex.  Most of all, he is dependable, his prices are reasonable and he is a gentlemen.  I would and have recommended him to others.
