Ken is an absolute, tech savvy pro; prompt, courteous and super helpful. He really souped up my 2011 MacBook Pro and saved me the cost of a new machine. Highly recommend!

Pj C. Newton, MA

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

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

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”.

Stewart Anderson Victorville, CA

This is the greatest company ever! They give 100% always! They go beyond customer service and expertise. Kevin has been my guru for many years and has never not been unable to fix my problem. I would never call anyone else, why would I when I have the best? I have sent many clients to him and will continue to do so. If I could do a higher rating than five, I would go all the way up!!

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 have been using Kevin for a number of years now and he always comes through for me. I would highly recommend Kevin as he is honest, fair and knowledgeable. He shows up on time and stays until his work is done and you are up and running with no issues on your computer.

Tami Menold Brea, 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.

Belinda Levin Tustin, CA

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.

Tamara Baker 20th Century Air Anaheim, CA

Kevin at Big K computers has been my “Go To” guy for years. Kevin is very professional, easy to communicate with and always on time. He makes life easy with working around your schedule. Kevin has helped me out with my Mac’s, windows desk top and phones. He always explains (in plain English, not the tech talk I don’t understand) what he is doing and what needs to happen to fix it. He offers solutions and does it in a timely manner. I recommend Kevin to all my friends and neighbors.

Cory Munro Anaheim Hills, 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.

Gary Miller Placentia, CA

Kevin is awesome! I highly recommend Kevin Harms from Big K Computer Service. He has been our computer “guy” for more than four years now and not only is he extremely knowledgeable, his customer service is excellent. He’s set up computers for us, solved problems, and even helped with the activation of our security system. Whenever we’ve had a question or problem he’s been available and is prompt for his appointments. He is definitely your “go to” guy.

Lenore Sommers Santa Ana, 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!
