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

Very professional, polite and knowledgeable. Very pleased with Ken’s demeanor and willingness to answer all my questions and concerns.

Jim Nashua, New Hampshire

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

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

Ken was extremely efficient and friendly. He told me everything I needed to know about the new software I had purchased. I would highly recommend him for anyone looking for an electronics expert. He completed the job flawlessly and in a timely manner. Thanks again Ken. My girlfriend and I were extremely impressed with your professionalism.

Nashua, NH

I am convinced that Mr. Kevin Harms and his Big K Mobile Computer Services company are both as good as it gets when I have needed computer services during these last 8 years that we have used his services in my dental office. We have 8 computer stations all interconnecting and of course issues come up unexpectedly.

We call Kevin. He communicates back right away. Whether it has been an emergency bug infection, or a computer needs replacement, or even the server needed totally upgrading, he appears as promised, always with a positive attitude, Kevin has done it very smoothly every time! He is a very well informed technician at computer structure. He is also a whiz at working with Microsoft Office and QuickBooks to make our computing such a headache-free routine in our office!

May you continue to prosper in your wonderful company!!

Tamara Baker 20th Century Air Anaheim, CA

We have been working with Kevin for several years. He successfully set-up the wireless networks in our office and home offices and connected all of our (many!) mobile devices. Whenever we run into computer trouble, he is only a phone call or text away. He is always reliable, on-time and guarantees his work. He is an excellent multi-tasker and able to work on several devices and issues at a time. Having reliable networking and mobile services is critical to our small business and Kevin helps to keep us up and running. He is very personable and a pleasure to work with!

Jill DeCriscio Alliance Outreach LLC Orange, CA

Kevin is a master mind when it comes to computers and any wiring services for cable, phone, etc. I have known him for 10 yrs. or more. He always shows up when he promises. No problem or challenge goes unsolved. He works quickly so you really get your money’s worth, and is always fair with his billing. He usually gives you an idea of how long a project should take so there’s no surprise at the end. He walks you through each step of the way to make sure you know how to get back up and running once he leaves. Whether you are setting up a new computer, monitor, or printer, have some odd error message, need to transfer data or set up new programs, set up a network, connect a second printer to fax or scan, or even experience a major crash, Kevin should be first on your list to call. He also will help set up an efficient and best value means of virus protection or data backup. I highly recommend Big K mobile for all your personal or business needs.

Larry Kleiman Larry Kleiman and Associates Los Alamitos, 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

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

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 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

Kevin in the past two years has been very helpful to me in resolving numerous hardware and software issues on my PC and printing device. He gives his customer good response time and is on time for his appointments. He is effective in diagnosing problems therefore doesn’t waste customer’s time.. He also offers warranty period.
For those reasons, I choose Kevin among other vendors to service my PC and accessories.

Susan Lin La Habra, 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

I’m one of those senior citizens that doesn’t know a great deal about the workings of a computer but Kevin is very understanding of any problems that I have. He patiently explains any concerns that I have. I like that he answers emails promptly and never seems to be rushing me. He is just all-around pleasant and knowledgeable.
