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

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

I’ve utilized Big K Mobile Computer’s excellent consulting and hardware services for my home computer needs since 2013. I’ve found Kevin to be honest and very knowledgeable. Kevin’s advice and help in the selection, acquisition, setup, use and maintenance of both hardware and software products has been extremely valuable. Service has always been prompt, excellent and reasonable. As a satisfied customer, I strongly recommend Big K Mobile Computer Services.

Larry Eggeman Anaheim, CA

We have been using Kevin for over 10 years. He is the best most knowledgeable computer tech we have ever had. We have never had a problem he couldn’t fix. He always returns phone calls promptly. He fixes our computers and if necessary orders new ones and sets them up for us. I have recommended him to at least 10 friends who thank me every time that they use him. I recommend him highly.

Gary Miller Placentia, CA

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

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 was recommended to me when my son’s computer was acting up. Kevin came out the next day after I called him, looked at the computer, said the computer probably had a couple of viruses and that the anti-virus software that was running was not all that powerful. He took the computer back to his shop spent a couple of days getting rid of the viruses, spiffing up windows, and making sure everything was up to par with the hardware and software. When he brought the computer back, he made that it was working properly, and then he did a run through on my computer to make sure it was working properly. Kevin also recommended a very highly rated and powerful anti-virus software, which we bought for both computers and have not regretted it purchasing it. It actually sped up my computer’s performance.

Needless to say I am very impressed with Kevin. I have used him often, and he even built me a computer that is still faster than most computers on the market today. Kevin is very responsive, answering emails and phone calls either the same day, or the next day when it’s after hours. Also he can explain what he is doing, or what is going on with the computer, to my “computer challenged” wife, so she can be home when I can’t be there.

I highly recommend Kevin! If you are having computer troubles, please give him a call.

John Braithwaite Long Beach, 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!!

Al Navas Sunwest Dental Long 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 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

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.

Ken was very professional and knowledgeable.

Yedi Koeshendi Nashua, NH

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

I was recommended to Big K Mobile by my neighbor. I called Kevin up and he came over in a day or so. When I opened my front door Kevin greeted me with a big smile,was very friendly and courteous. We proceeded to my office and within 25 feet of my pc he said your computer does not have any mechanical problems. I said how can you tell so fast and he told me over time that he has acquired an hear for sounds in a pc, That really impressed me. Kevin was able to take my computer away and bring it back in 2 days, completely overhauled, and running great WOW! Since then I’ve called Kevin on several occasions and he has been able to answer my questions and has not charged me extra. Kevin goes above and beyond for his business which shows me his dedication to his profession. We will continue to use Kevin and also to refer Big K Mobile to our friends.
