He repaired my Asus UX430U after the battery stopped holding a charge and took the time to clearly explain what was wrong and exactly what I was paying for. I never felt rushed or talked down to. When I asked for recommendations on buying a new laptop, he shared thoughtful, practical advice on which models to consider and the best times to buy, like Black Friday or Cyber Monday. He's a solid human, does honest work, and I genuinely enjoy supporting his small business.

After a pet-related mishap caused my son's computer to shut down I decided to contact Sam & Marcus…read morewith Expert Reaction based on them being local, and very highly rated here on Yelp. While they do "house-calls" this issue was a bit more serious, and so I coordinated with Marcus to drop off the computer so he could trouble-shoot the problem. (Note: their current location IS inside the yard for the auto body workshop.) I also left them with the brand new PSU I'd bought from Newegg, thinking it may have been the problem, but wisely deciding to use their services rather than have a go at it on my own. Because as it turned out it was NOT the PSU, but the motherboard and RAM, and after replacing those components Sam and Marcus were able to get the PC up & running. They also very considerately did not even open the PSU box, even leaving its shrinkwrap intact, making it an easy RMA for me. The lads stayed in contact with me during the entire process, which took a little over a week, from the initial diagnosis, to sourcing the new components, the installation, and then 'burn-in' to make sure there were no other issues. At the end of the day they get a well deserved, well-earned 5-star review. "Pet-mishap", remember? Let's say it was of "the worst kind" and leave it at that. Thanks Sam and Marcus! Your services are very much appreciated!

I was worried it would require a major repair. I was greeted by Johnson, and he immediately knew what to check, diagnosed the problem within minutes, and fixed it quickly. What impressed me most was Johnson's expertise, honesty, and transparency. He didn't try to sell me unnecessary services or make the problem sound more complicated than it was. He explained the issue, resolved it efficiently, and charged a very fair price. It's refreshing to find a repair shop that is knowledgeable, trustworthy, and genuinely focused on helping the customer. I highly recommend this place and Johnson for computer and laptop repairs, in addition to phones!

If you need your computer repaired this is the place to go! From the moment I put in my online inquiry through the Yelp message system, I felt at ease and was told what to do before bringing in my computer, what the possibilities are and a quick pricing quote. I still can't believe how quick the water damage was repaired on my MacBook Pro, a lot quicker than I expected. I was prepared to lose my data but he managed to repair the motherboard and there were no data loss at all! Also, the price is reasonable and affordable compared to what Apple store quoted me which would have resulted in data loss. Joseph, you are a lifesaver!!!

If they are available to repair anything we repaired laptops with him, phones iPads, and probably other things I forgot it at this point, but he always comes through.

He is literally the guy to call for any tech needs you may have. I have his number saved on my phone and I know I have a couple of jobs pending for him as well.

Within two minutes, the employee (I believe his name was Josh) redirected me to the owner. The owner wasn't there. No offer to schedule anything, no follow-up, nothing. I asked about laptop pricing and whether they could compete with Amazon. He said yes, they can match prices. Fine. But the entire interaction felt rushed, like he had somewhere better to be. No effort to actually help me understand anything or earn the business. That's the thing. I was ready to spend money. On a consultation, on a laptop, potentially both. But when an employee doesn't own the outcome, it shows. The owner should know that customers willing to pay are walking out the door because the person on the floor doesn't seem to care either way. Left with nothing. Spent nothing. Completely avoidable.
