David Bangura Nashua, NH

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 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

Kevin with Big K Mobile Computer Services is by far the most reputable and ethical computer service technician I have ever worked with. Owning my own business for over 11 years has given me many comparative experiences with other computer technicians. I can honestly say that I have experienced only top notch service and I have complete confidence in Big K’s reliability, promptness in returning my calls for urgent matters, efficiency and expertise with ALL things technical. Big K has helped me with my Apple TV set up, my home and office computers, both Mac and PC, and my iPhone. I have so much faith in Kevin of Big K, that I have referred many of my friends, family and clients to him. I have unwavering trust and confidence in Big K Mobile Computer Services.

Lynda Witt Proactive Health Solutions Tucson, AZ

He was knowledgeable and VERY helpful. I received excellent and prompt service. Any time I had trouble, I would receive a response within an hour. If he could not fix it over the phone. He would be there the next day to fix the problem.

Thank you for your over the top work!

Ian Waugh Corona, CA

I’ve utilized Big K Mobile Computer’s excellent consulting and hardware services for my home computer needs since 2013. I’ve found Kevin to be honest and very knowledgeable. Kevin’s advice and help in the selection, acquisition, setup, use and maintenance of both hardware and software products has been extremely valuable. Service has always been prompt, excellent and reasonable. As a satisfied customer, I strongly recommend Big K Mobile Computer Services.

Larry Eggeman Anaheim, CA

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

I’ve known Kevin for about eight years. He’s polite and courteous. Kevin knows his job well. He makes house calls which is convenient instead of you having to to take your computer to and office. I’ve had him work on my MAC’s and help me get my granddaughters’ PC’s set up and running and even added an Anti-Virus on both PC’s. I have to agree with a review I just read that he keeps everyone smiling while he is at my home working on the computers. If you have a problem with getting a computer loaded correctly or need stuff transferred off your old computer to an external hard drive give Kevin a call. I highly recommend him.

Alice McDonald Cypress, CA

I would not use anyone else!!!!

Connie Papple 20th Century Air Anaheim, CA

Best Computer Guy! Totally reliable. I have used this company for many years & refer them out constantly. Kevin is very honest and always willing to help me with any computer issues I have.

Tiffany Cassity Fountain Valley, CA

Kevin is very personable, fair, and does a great job. He works quickly but also spends extra time with projects, even when not expected. Kevin seems to go out of his way to be helpful and friendly. I would highly recommend him to anyone.

Cameron Andrews ProActive Physical Therapy Orange, 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

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

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.
