Stewart Anderson Victorville, 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.

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.

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!

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.

Yedi Koeshendi 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!

Kathleen Kennedy Lake Forest, CA

Big K Mobile Computer is the best. Kevin is extremely knowledgeable and stands behind his services. He will never suggest anything for ones computer that isn’t needed. Kevin is so professional and extremely easy to get hold of and work with. He shares what he is doing in non computer lingo which is great for those who feel lost in the tech world! I would without hesitation recommend Big K to anyone who needs a “computer doctor”.

Joan Ash Stanton, 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

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

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.
