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

Hiring Big K Computers for my small business was the best decision I made. I met him 14 years ago and appreciate his OUTSTANDING customer service and technological expertise. I have a very small business and rely on his knowledge to help me find the answers I need that also fits my budget. Kevin has taken the time to understand my business needs and makes recommendations accordingly; not over-selling unnecessary hardware or software. I trust him fully and recommend him OFTEN to friends and family.

Brenda Witt Proactive Health Solutions Costa Mesa, 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

Big K Mobile Computer is the best. Kevin is extremely knowledgeable and stands behind his services. He will never suggest anything for ones computer that isn’t needed. Kevin is so professional and extremely easy to get hold of and work with. He shares what he is doing in non computer lingo which is great for those who feel lost in the tech world! I would without hesitation recommend Big K to anyone who needs a “computer doctor”.

Joan Ash Stanton, 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 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.

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 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.

Big K, Kevin is great!
I’ve been using his services for at least fifteen years. He is friendly and courteous. He knows everything tech. He is knowledgeable about all kinds of hardware and software. If you know a lot about tech, or not so much, like me, he’s your guy. I’ve never had a problem he couldn’t solve.

Stewart Anderson Victorville, 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

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 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.
