Not only did he reassure me that he'd take care of it, but he got my laptop back to me the same day.

Multiple staff members in my office have complained of his rudeness and recently his comments are dominated by his desire to avoid taking responsibility for anything. I understand that the distance is difficult for him so I had offered to transition to someone else as soon as he completes the current project of setting up our new computer that he committed to, but instead he is abandoning that project leaving us without assistance and at risk of "do it yourself wrong," as another person said. Completely unprofessional.

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.

My HOA hired this firm to install a security camera system and this was one of the worst…read moreexperiences I've ever had with a services provider. I do not recommend this company in any way, shape or form. The cost was high, the quality was beyond poor and the system never really worked right. It's been a few years now, and I happened to come across this firm on Yelp and still felt the need to expose them. That's how bad my experience was. I do see some good reviews, but they're all related to computer issues so perhaps Genus won't completely screw you there. As for security systems, run away! First of all, the equipment installed was outdated nearly as soon as it was installed. Secondly, the installers seemed to be guys hired off the street w/o any skill level which lead to a very poor install. Thirdly, the customer service is horrible as when I brought my legitimate complaints to Mike Mora, he refused to work with me to resolve them. The funny thing is that we didn't go with the lowest bid, in part, to avoid some of these issues. Bottom line: Do not use and/or trust Genus or Mike Mora.

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.
