I found this place on Yelp, sent a message, within a less than a minute, I got a quoted price, what time to come in and roughly how long it would take. No BS, no "we'll have to see what condition the phone is in, in order to give you the price", just exact price right on the spot. I came in at the exact appointment time, and to my surprise Jerry, the manager was there waiting for me. Dropped off the phone to him, he told me to come back in 30-45 minutes. He didn't give me any paper or receipt, so I felt a bit worried since there was no proof I left it with him but I did so anyways. Came back 45 minutes later and there was Jerry waiting for me again, showed me the phone and it was a brand new screen, worked even better than before and i was out the door in a few minutes. One of the best experiences I've ever had with repair service and definitely making this my new go to place for any repairs. I also found out Jerry not only does Phone repairs but also, tablet, and computer so I'll be coming here for those in the future. 5 stars for awesome experience here, and another 5 stars for Jerry for being friendly, easy to deal with and just providing good customer service.

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.

I did not know it at the time but the pump had failed leading to my CPU (i9 12900k) redline for the subsequent 4 months - by the time it was May, my computer would regularly screen tear during VR, crash during games, and I was at my wit's end. I tried everything on my own until I followed up with Jose at APlus Tech Labs. He identified the issue, offered up upgrade my CPU and replace it with a new AIO Cooling system. I was very happy with the price and lead time. I wound up bringing Jose my 2nd PC as well! For this 2nd PC, the PSU or the Motherboard had gotten fried so we had both replaced in a matter of days. I really appreciate the communication and he was even able to meet me afterhours as I was unable to come during regular business hours while I had a deadline to meet to get this 2nd PC set up at home. Thank you, Jose. Appreciate what you do!~

For awhile (months) my PC has been losing video while playing games or video chatting. I swapped out parts in and out and same issue was happening. Decided to take it in to have a professional diagnose the issue. Walked in. Technician was helping someone at the time and acknowledge me. We talked about the issue I was having and provided the servicing cost which I feel was fair (~$100). Gave me a 2-day estimate for servicing. After 2 days the technician gave me a call that my PC is ready to be picked up. At the store he gone over the issue (which is an incorrectly plugged in power supply wire which I completely overlooked). PC is running very smooth. No issue ever since taking my PC in. All software running with no issue. No more power issue. No more stress. Will not hesitate to come to Kaddy's for any future PC issues.

Let's start with the positives, which is how quick Earl is at responding to requests. But that's…read moreabout the only nice thing I can say here because I have very strong suspicions that I was almost taken advantage of when I saw the cost estimate. I was quoted an estimated $540.66 to upgrade my laptop's RAM and SSD. While I am fully aware that computer part prices have skyrocketed because of AI, charging $179 for a stick of 16GB DDR4 RAM and $176.66 for a 512GB SSD is pretty extreme. The only thing that is reasonable is the labor fees since a Micro Center store would charge about the same for a RAM upgrade and changing out an SSD. However, the cost estimate costing more than what my device costs seems predatory. I would have just bought a new computer for $540. I took my device to another shop called Wizfix Computers to get another quote, and the owner of WizFix said that $540 for the same upgrades is a gross overcharge. I was only charged $345 at WizFix ($225 for the same parts plus tax, $120 for labor). And as a bonus, the OS was upgraded to Windows 11. Device has been running well after the upgrades. I would have been overcharged nearly $200 if I chose Ross Tech. Trying to take advantage of someone like this to make extra money is very unethical and bad business.

Expert Reaction had 5-stars so I decided to give them a try. First of all, we're both in Covina and they offer free pick up and delivery. Marcus, the tech, explained that diagnostics are $99 which would be applied to any repairs. After he got started he sent me several texts to let me know what he was finding and what he would be doing. He determined that it was badly corrupted and he'd need to reformat the hard drive and reinstall Windows. (If you don't back up your files like I do everything could be gone forever.) He also checked for hardware problems even after determining that it was software just in case. End of the story is that I got a like-new PC for $170, when I feared that I was going to have to buy a new one. All companies should operate like this one does - and I would say that even if they hadn't been able to fix it.
