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

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 entrusted our family computers exclusively to Bid K Mobile Computer for a number of years. Our investment in Kevin has and continues to pay off handsomely. Kevin consistently goes the extra mile; prompt return of calls, making and keeping appointments, thorough knowledge and application of his craft, courteous service, and most importantly a willingness to demystify and answer our lay questions surrounding computer issues. We unhesitatingly would refer Big K to anyone with full assurance that Kevin will fully validate our recommendation.

Lynn & Wyla Saracino Anaheim Hills, CA

Terrific person and service. Thoughtful advice, helpful explanations, prompt, generous with his time, goes out of his way to come to our house when needed.

Steven V. Lexington, MA

This guy is dedicated, he drove in the snow in order to keep my appointment. Quality job, he is very professional and take great pride in quality. good job!!!!!

David Bangura Nashua, NH

A friend recommended Kevin to us and we in turn recommended him to other friends for many reasons. He is very conscientious in returning voice mail and email messages, makes every effort to schedule a convenient appointment time (How much easier is it to have him come to your residence or business instead of carrying your computer somewhere?), is very prompt, personable and professional. We appreciate his patience in working with our 14-year-old grandson and with us 75-year-old grandparents. His people skills and his ability to explain and teach are awesome! He goes out of his way to assist in any way he can.

Roger Duthoy Yorba Linda, 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

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

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

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!

Christine Baker Orange, CA

If you are looking for a computer technician who is reliable, trustworthy, safe and simply the best, you have come to the right place. Kevin and Big K Mobile Computer Service has made fixing computer issues a phone call away. Kevin has helped me with my computer and home IT needs for nearly 10 years. He is prompt, professional and ALWAYS goes the extra mile. Being able to have a mobile service come to your home makes a daunting task easier to deal with. His knowledge and expertise is incredible and I can’t say enough good things about Kevin!

Doris Fults Buena Park, 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

We have used Kevin for over five years and has yet to disappoint us. He has always been reliable, knowledgeable , pleasant and always on time. He has a very high work ethic and takes an interest in his clients. You can always count on Kevin to fix your computer problem.
We feel fortunate to have him as a tech resource. He is completely trust worthy.
Kevin is our go to guy.

Stewart Anderson Victorville, CA

Ken is a consummate pro; completely knowledgeable, friendly, on-time, and totally helpful. Not only did he do a wonderful job with the installation, he offered suggestions as to how I could further boost my laptop’s performance. I highly recommend Ken to any serious user. FIVE STAR GUY!!

PJ C. Nashua, NH

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

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!!
