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

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.

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.

Big K Mobile Computer Services is my go to for purchasing computers or any computer related issues. Kevin is an all around great guy. Professional, dependable, personable, reasonable AND he can work and talk at the same time! TicToc. When my work computer goes south on me, I send an SOS to Kevin and when he walks through the door my anxiety level goes back to normal, because I know my computer is in good hands and that the issue will be addressed quickly. Big K performs regular maintenance on my work and personal computers, so that really cuts down on issues and fire drills. No better computer than one that doesn’t fight back 🙂 I found Big K years ago through a referral and I couldn’t be more pleased. You will be too!

Stewart Anderson Victorville, CA

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

Ken is an absolute, tech savvy pro; prompt, courteous and super helpful. He really souped up my 2011 MacBook Pro and saved me the cost of a new machine. Highly recommend!

Pj C. Newton, MA

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 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

This is the greatest company ever! They give 100% always! They go beyond customer service and expertise. Kevin has been my guru for many years and has never not been unable to fix my problem. I would never call anyone else, why would I when I have the best? I have sent many clients to him and will continue to do so. If I could do a higher rating than five, I would go all the way up!!

Linda Walker Anaheim, 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

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 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

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

If you are looking for a computer technician who is reliable, trustworthy, safe and simply the best, you have come to the right place. Kevin and Big K Mobile Computer Service has made fixing computer issues a phone call away. Kevin has helped me with my computer and home IT needs for nearly 10 years. He is prompt, professional and ALWAYS goes the extra mile. Being able to have a mobile service come to your home makes a daunting task easier to deal with. His knowledge and expertise is incredible and I can’t say enough good things about Kevin!

Doris Fults Buena Park, 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.
