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

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

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!

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

Ken was very professional and knowledgeable.

Yedi Koeshendi Nashua, NH

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.

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

I have had Kevin and Big K service all of my Tech needs for over 15 years. This includes home and business. I have found him to not only be knowledgeable about anything Tech, but fair and personable too. He is now our family computer “go to” guy too as my four daughters and son-in-laws set up their home and business tech smart homes too. I have been recommending him for years to family and friends and I have always had only “thank you so much for recommending Kevin and Big K”. I have always felt that satisfied customer referrals are a mark of a great company.

Robert Phelps Huntington Beach, 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 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

Kevin came highly recommended to me over 5 years ago by another firm and he is simply terrific. I work from home, on several computers, with multiple operating systems and have exceptionally high document volume and trust Kevin 1,000% to keep everything running smoothly. And when I have a technical issue (usually operator error) or need any kind of computer related assistance, Kevin has always provided tremendous customer service! It is also important Kevin gets right down to business when he arrives – you get more than you pay for! You will not be disappointed!

Kathleen Kennedy Lake Forest, CA

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.

Shelley Mager Santa Ana, 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

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

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 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!!
