David Bangura Nashua, NH

Kevin of Big K Mobile Computer Services has been a life saver for me many times. Whether it’s solving computer issues, helping me set up my new computer, transferring data, setting up modem/router, printer, syncing my iPods, iPhone or Apple TV, Kevin is a top-notch IT professional. It gives me such peace of mind to know I can always call Kevin to help me any time I have questions or need help with any of my electronic needs.

Penny Batelli Tucson, AZ

Our company has been working with Kevin for around six years now and it’s tough to put into words how appreciative and impressed we have been with his work. I’m not kidding when I say we’ve hired and fired no less than 5+ external computer technicians before finding Kevin… he was a godsend for our company. Kevin has helped with everything in our office ranging from computer issues to server setup and he’s always been nothing but professional. Kevin also has to been the only computer technician in America that has everyone in the office smiling the second he walks in until the time he walks out the door. He’s genuinely a great guy and knows what he’s doing; he’s upfront and truly does look out for the client whereas many in this field are simply looking to take advantage. I’m done gushing now… give him a call and you won’t turn back. Kev is the man!

Ted Slaughter RealSource Partners Newport Beach, 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

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

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

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.

Alice McDonald Cypress, 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

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!

Debra Munson Pamela M Smith Security Seminars Inc. Whittier, 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

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

Kevin is our go to guy.

Stewart Anderson Victorville, CA

We have entrusted our family computers exclusively to Bid K Mobile Computer for a number of years. Our investment in Kevin has and continues to pay off handsomely. Kevin consistently goes the extra mile; prompt return of calls, making and keeping appointments, thorough knowledge and application of his craft, courteous service, and most importantly a willingness to demystify and answer our lay questions surrounding computer issues. We unhesitatingly would refer Big K to anyone with full assurance that Kevin will fully validate our recommendation.

Lynn & Wyla Saracino Anaheim Hills, CA

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!

Jill DeCriscio Alliance Outreach LLC Orange, 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.
