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

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 stumbled upon Kevin many years ago when our office needed an expert for our computer systems. From the start, he was reliable, accessible, knowledgeable, professional and personable. We always looked forward to working with him. He was always so patient and kind. I have also employed him to work on my home computers. He is trustworthy, honest and responsible. I don’t know what I would do without him! He is a very special person. I highly recommend him!

Donna Metcalfe Vice President, Teamsters Union Local 952 Orange, 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.

Brenda Witt Proactive Health Solutions Costa Mesa, 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!

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 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 has helped me with my private practice law firm computer network for 3-4 years. I used several other firms previously and Big K stands out as the best by far. Kevin is knowledgeable, reliable, responsive, practical and personable. He is always there when I need him and the best recommendation I can give is that I trust him completely. I recommend Big K without any reservations.

Paul Minerich Paul Minerich ESQ. Santa Ana, 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

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

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 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.
