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

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

Kevin IS as good as it gets. Tremendously knowledgeable, always on time, never rushed to leave, very personable and trustworthy. His charges are quite reasonable and one never has to be concerned about Kevin trying to sell you anything that is not needed, i.e., gadgets you don’t understand or appointments you don’t need. A joy to have in the house, he’s been a hit with every member of our family. You could not have a better Tech expert!

Ashby Jones Santa Ana, 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

I have been working with Kevin Harms for three of the six years I have had my MAC computer. Before I was referred to Kevin, who is not even in the same state as I am, I had used many local people. None of these people really were helpful. With Kevin, I e mail him, we set up a phone appointment, he gets in on team viewer and does what I need and he is always reasonable with his charges. I have recommended him when someone needs a MAC guy because I do not think there is any one better!

Marilyn Day Tucson, AZ

Kevin is the best. He has been servicing my computer needs for years and I can’t say enough about his knowledge of what I need. I work from home and need a network that works for me and my busy family. He is prompt and professional. I have recommended him to so many friends and they are all so happy. You can’t go wrong with Kevin.

Jill Munro Tustin, 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.

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.

Gary Miller Placentia, CA

Best Computer Guy! Totally reliable. I have used this company for many years & refer them out constantly. Kevin is very honest and always willing to help me with any computer issues I have.

Tiffany Cassity Fountain Valley, CA

As a couple of “less than tech-savvy” seniors, we have relied upon Kevin for several years and are happy to tell all that they can’t go wrong with Kevin! He is friendly, responsive, has reasonable rates, goes out of his way to make sure we understand what the problem is, and is very thoughtful in suggesting solutions and giving options, knowing we are on a tight budget. He is a unique combination of a smart, technically proficient professional combined with a “you feel a friend is visiting” kind of demeanor. He truly deserves five stars!

Linda Wolff Santa Ana, CA

Kevin at Big K has been setting up and servicing my computer, printer, cell and tv for years. He is very professional, knowledgeable and reasonable. I would recommend his services to anyone.

Linda Oster Anaheim, 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

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!
