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

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.

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.

James Matthews Buena Park, CA

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.

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

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

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.

John Braithwaite Long Beach, 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.

Nonnie V. Fullerton, 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 have been using Big K Mobile Computer Services for several years now and I couldn’t be more satisfied . Kevin is very personable, professional and prompt. Having someone come to you instead of having to take your computer in for service or repairs is a big plus for me. Kevin takes the time to explain what he is doing and why in terms I can understand. His rates are very reasonable, especially when you consider that he comes to you and the excellent level of service he provides. When it comes to computer repair and servicing Kevin will always be my go to guy and I hope anyone reading this review will Give Big K a chance at your business. You won’t be disappointed!

Don Metzger Costa Mesa, 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.

Robert Phelps Huntington Beach, CA

Ken was very professional and knowledgeable.

Yedi Koeshendi Nashua, NH

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.

Arnold Mahler Villa 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.
