Mr. Kim is an absolute professional and without question knowledgeable in every aspect of the profession, which I'm rather illiterate. However, he guided and explained every detail and repaired my Mac Battery. My instrument is rather old and I'm in favor of replacing it in the very near future. WITHOUT QUESTION HIS KNOWLEDGE AND PROFESSION WITH COMPUTERS AND IT ARE SECOND TO NONE. Mits 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.

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

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

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

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

Great service and the price of repairs is affordable. I have been to other computer repair retailers but this one is the best by far. I definitely will recommend to my family members and colleagues. Thank you! read more

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

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