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

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

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

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

Kevin IS as good as it gets. Tremendously knowledgeable, always on time, never rushed to leave, very personable and trustworthy. His charges are quite reasonable and one never has to be concerned about Kevin trying to sell you anything that is not needed, i.e., gadgets you don’t understand or appointments you don’t need. A joy to have in the house, he’s been a hit with every member of our family. You could not have a better Tech expert!

Ashby Jones Santa Ana, CA

Our company has been working with Kevin for around six years now and it’s tough to put into words how appreciative and impressed we have been with his work. I’m not kidding when I say we’ve hired and fired no less than 5+ external computer technicians before finding Kevin… he was a godsend for our company. Kevin has helped with everything in our office ranging from computer issues to server setup and he’s always been nothing but professional. Kevin also has to been the only computer technician in America that has everyone in the office smiling the second he walks in until the time he walks out the door. He’s genuinely a great guy and knows what he’s doing; he’s upfront and truly does look out for the client whereas many in this field are simply looking to take advantage. I’m done gushing now… give him a call and you won’t turn back. Kev is the man!

Ted Slaughter RealSource Partners Newport Beach, CA

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

Kevin is a great guy and does great work. Any time I have a problem he solves it in a efficient manner and in a prompt time. I would highly recommend his service.

Gary Miller Placentia, 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

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

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

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.

Tiffany Cassity Fountain Valley, CA

I am so glad a friend recommended Big K Mobile Computer Services to me. I have used Kevin for at least 5 years and I trust him completely. He has hooked up my new i Mac, and my new Smart T.V., as well as taken care of any problems I have had with my computer, iPad, and/or iPhone. It is so nice to call or email him to set up an appointment, have him arrive on time and take care of everything. He is very easy to talk to and understand. He never talks down to me and has a great sense of humor. I highly recommend his services. (And he gives senior discounts!) I agree with all the previous 5 star reviews. He’s terrific!
