Kevin at Big K Computers came highly recommended to me. I had issues with my security software for my business, so when it was time to renew, I had him do a complete diagnostic on my system, and install new security software. I’m glad I did. Here’s why I will always turn to Kevin for anything technology-related:

* His expertise and experience are off-the-charts …not just with computers, but smart devices, TVs, web services, products, etc.
* He shares his knowledge in terms you can understand …and gives you tips + practical advice
* He offers personal service and comes to you to do the work on-site
* He’s very thorough and methodical …but works relatively fast
* He stands by his work and follows-through
* He’s responsive and accessible …I can call, text or email him at any time with a question
* He’s very competitively priced and doesn’t “sell” you on anything …He just gets the job done
* He is easy to work with, keeps you up and running, and you can trust him

I was so satisfied with Kevin’s work that I had him do diagnostics and install security software on all the computers used by my family. I’ve referred him to relatives and friends who have all be very satisfied. So anyone who is in need of top-notch technical support service – Kevin is your guy.

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.

Lois Heidner Buena 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

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

Kevin at Big K computers has been my “Go To” guy for years. Kevin is very professional, easy to communicate with and always on time. He makes life easy with working around your schedule. Kevin has helped me out with my Mac’s, windows desk top and phones. He always explains (in plain English, not the tech talk I don’t understand) what he is doing and what needs to happen to fix it. He offers solutions and does it in a timely manner. I recommend Kevin to all my friends and neighbors.

Cory Munro Anaheim Hills, 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

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.

Tom Griffthe Anaheim, CA

I don’t know where I’d be without Kevin.  He sets up and solves all my computer and printer problems, plus he set up my new televisions and netflex.  Most of all, he is dependable, his prices are reasonable and he is a gentlemen.  I would and have recommended him to others.

Amy Curtis Laguna Niguel, 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.
