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 want to first start off by letting everyone know how awesome Kevin is as a computer tech. I found him probably around 4 years ago, when my one of my computers at my business was giving me problems. He is so efficient on how he handles his arrival times, its so refreshing to deal with someone who does exactly what they say they will do. He is really upbeat and funny while always working and getting the job done quickly. He even will let you call him on a small problem that he thinks he can walk you through at no charge. I totally recommend Kevin to anyone needing mobile computer service at a fair price. Thanks Kevin.

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.

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!

Amy Curtis Laguna Niguel, 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!

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.
