The microscope works properly. I just started repairing clocks. Or the clock is defective. But with it I can see all these tiny details on a 50 inch monitor and it makes things a lot easier. The only complaint is that the cable is 12 inches long. If you're like me and your computer isn't a laptop or you don't want to use your keyboard as a work surface, you'll need a much longer cable. so keep that in mind. says he has WIFI for tablets and phones. Yes, it works, but I want my projects to be shown on a big screen, so I'm sticking with the old-school wired method. I recommend this to anyone who has a hobby or just wants to look at things up close.
