Pro: Very nice and efficient. Price is very reasonable and clear on each steps/ possible outcomes If you're in Diamond Bar, he can even meet you and drop off somewhere close to you Con: Only little issue, be sure to call before going to the place. The owner goes around the cities doing his jobs, so business hours do not necessarily mean that he's at the Nogales location read more

Joey did an amazing job fixing my computer's overheating issue. He made the entire process incredibly easy by coming to pick up my computer and dropping it back off once it was repaired. He was friendly, professional, and kept me updated throughout the process. His pickup and delivery service is super convenient, and it's clear he genuinely cares about providing great customer service. I highly recommend Joey to anyone looking for reliable and hassle-free computer repair! read more

ABOUT A MONTH OVERDUE (10/22/25 - 10/24/25): My step son had his laptop in his room as a food tray for the past 2 years. The laptop was a high end Dell from 2023, however, it was ultimately out of commission and collecting dust due to the screen he broke. With Joey of WizFix Computers' help, the laptop LIVES AGAIN. Once you speak with him and he is able to diagnose your device issues, you can easily tell that he is passionate about his work. That passion clearly translates to quality work and thorough repairs on the gadgets presented to him. He will diagnose and look any additional issues you may have so you can be aware of pending issues. His prices are extremely reasonable as well and he does quality work. You won't be disappointed with his services so go ahead and give him a call... read more

I had my old MacBook Pro 2012 laptop battery replaced at WizFix Computers and Kuya Joey was a total pro! He was super helpful, explained everything I needed to know clearly, and got the job done quickly and efficiently, despite some shipping delays of battery (it was over the weekend, so understandable). Easy payment thru Zelle. He was friendly and made me feel at ease and was flexible with scheduling drop off/pickups. Thanks, Kuya Joey! You're the best! **Rating:** 5/5 stars read more

We loved working with Joey. Our office had a bad power outage and our ancient server computer was not operational. I took it to Joey and he had it up and running in a day + he took care of other issues with the server. Highly recommended for all computer issues. He was very responsive and updated me regularly. Price was very reasonable. read more

I called Joey for a quote to upgrade our inexpensive HP laptop. It had a small hard drive and only 8 GB RAM. He wasn't at his office on Nogales, but we agreed to meet near our home in Diamond Bar at the Chevron Gas Station across from the high school. I told him I wanted a bigger hard drive and more RAM. He opened the laptop and kicked the tires, so to speak. After checking it out he made recommendations on which we agreed. 27 hours later, I met him back at the gas station to receive our upgraded laptop. I paid him with Zelle and was very pleased with his service. Now we have a virtually new, more powerful laptop for a fraction of the cost of a new one! read more

I broke my DC Input cable on my monitor and Joey did an amazing job helping me get the port fixed. He was very transparent with pricing, timing, and whether or not it would be worth getting it fixed vs just buying a new monitor. I was always able to reach him with any questions, and while he was ordering parts for me he kept me updated each step of the way. It's been over a month since he repaired my monitor and there hasn't been any issue. He's super friendly and if I have any future computer problems I'd go straight to this store read more

When my laptop kept shutting down within the first minute after booting up, I brought it to Joey in a rush to get it fixed to take my online exams. He did an amazing job fixing it within a couple days in time for my exams while giving me a fair price. I was notified of the whole process from start to finish on what the problem possibly was, possible solutions with prices, and when I would be able to have the laptop. Overall, Joey is extremely friendly and knowledgeable in his craft. It has been a few weeks and no issues with my laptop anymore. read more

Joey is the go-to tech if you have any concerns about your PC or laptop. Fast, efficient, and reasonable prices are reasons why I keep going back to him. I had a gaming PC where it would re-boot to BIOS continuously and I thought I was going to purchase new SSD's but Joey came through and fixed the issue. I brought it in about 10AM and he was done by 3PM. He also was able to install some hard drives I needed done in Raid 0. No issues at all. It was done the same day and he charged me at a very reasonable price. Don't hesitate to bring your electronics here. Joey is top notch. He's always in constant communication as well so you'll be getting updates regularly so you're not kept in the dark. I'll be going back again for sure. Thanks Joey! read more

I took my laptop to another repair shop previously and they told me to just buy a new laptop instead. I am happy with the service and would highly recommend any computer related issues to give Joey a chance to help. read more

LONG REVIEW BECAUSE I FEEL SO BLESSED!!! Joey had fixed my son's computer super fast and for an outstanding price. It runs like new. I have an old laptop I refuse to give up because of my type of work. Stupid Norton suggested I do a driver update, and I got the blue screen of death. In safemode with networking -- because the laptop would not open "normal" -- Norton could not help me with a virtual takeover. I had done a big transcript that took two weeks to do, so I was upset and scared of blowing a deadline and losing two weeks worth of hard work along with a client - who would hate me. JOEY TO THE RESCUE! He is so honest and knowledgeable. THIS GUY IS REAL!!!!!!!!! I had my laptop repaired a few years ago and could have bought a new one with the price I was charged. Joey charged a fraction of the price and did he did WAY MORE and way faster! I still could not believe how fast he fixed it. He did all types of upgrades that did not change the way my laptop works. I HATE CHANGE! I was a Windows 7 holdout, but he convinced me to upgrade to 10, which I had to because there were so many issues that started to occur because of old browsers, etc. I have a new computer with Windows 10, but I hate it and I want to tear my hair out when I use it. Don't get me started with Windows 11. I did a trial run on one, and it sucks! I HAD TO FIX my old one, even if it was just to try to save the job I did and not piss off a client by running late. I WOULD HAVE BEEN DONE WITH THAT CLIENT AND PROBABLY IN TROUBLE. I WAS in awe when I brought it home and it worked like new, but faster! He is such a great tech! My steno machine connected right away and Stenocat totally took the upgrades and works even faster because of what he did. I DID NOT LOSE MY TRANSCRIPT and I met my deadline. God bless this man!!! I put my faith in God and He helped me by bring Joey into our lives. FYI: His shop is a tiny little place, so you do not get stuck helping him pay his rent. You will not be sorry if you go to him. I promise to God. read more

Joey is a one man band. I came to him when my computer was not projecting an image on my monitor. He helped me retrieve all of my important files. He also helped get rid of the old computer since I had already bought a replacement. I came to him again when I broke my USB in half! Something so small and fragile, yet so vital the day before an exam and presentation! He helped put it back together and was able to retrieve my files again! What I like about Joey is that he is determined. Every job that he does is like a new puzzle waiting to be solved. He doesnt promise anything, but he always tries. I am definitely a loyal customer and recommend him to everyone! Especially if your looking for someone affordable. read more

Joey was highly recommended. With this pandemic. I need a new computer but could not afford one. Joey was able to upgrade me 2011 Acer dinosaur. Joey was very kind and thoughtful. He gave me a new mouse to keep up with my Zoom meetings and future classes that I need to take. I don't expect to have a super high performance but he runs just fine with my new Microsoft 10. Thank you Joey. read more

Thank you Joey! I really appreciate the time and effort you took while fixing my Mac book.

I've been going to Joey for a years now. My uncle told me about him and my mom took her laptop in one day and got it fixed really fast and for a reasonable price. I work next door to him and he is very nice, very professional and nice to talk to. He even lets me use his computer to do some work or printing. Joey actually sells HP ink, color or black. Besides selling ink and fixing computers, he also makes keys. I found out that he also does "ads." Like newspaper type ads for $8 a month. Put your ads and be advertised locally. read more
