I can't say enough good things about Joseph at All Electronics in Upland. I'm a professional…read morephotographer and business owner, and my cameras are literally part of my livelihood. I shoot everything from movie sets and red-carpet events to other professional photography jobs, so when my equipment goes down, I need someone I can trust. I brought Joseph two Canon R6 camera bodies, one that I normally use with my 24-70mm and the other with my 70-200mm. Both cameras had loose hot shoe mounts, which was causing my flashes to lose connection. I was having to physically hold the flash down just to get it to fire. As you can imagine, trying to hold a flash down while zooming, shooting, and working a live event made my job extremely difficult, and I was getting dark images whenever the flash lost connection. I found Joseph through Google, explained my situation, and told him how important these cameras are to my business and that I needed them back ASAP. Joseph came through big time. He took care of BOTH cameras and had them fixed within a matter of hours, the SAME DAY. Beyond the repair itself, what stood out to me was how Joseph treated me. He was professional, respectful, kind, and genuinely seemed to understand how important my equipment was to me. That kind of customer service is hard to find. Joseph, thank you again for taking care of me and getting me back to work so quickly. You definitely earned my business, and I would recommend you to other photographers who need their equipment repaired.

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!
