I bought this SMD micro soldering and pcb inspection...look, it’s a sub $100 microscope...and for the money, I didn’t expect it to be so usable! The picture is amazing, and the infinite zoom is awesome. It has the slightest bit of input lag, but after just a day of messing around, I can touch my soldering iron to even the smallest capacitors just looking at the screen. I was expecting it to only be good for PCB inspection, but I am definitely able to solder even the smallest components with this with no Trouble at all. Honestly, I don’t see you finding a more usable scope unless you want to drop an extra 2 or 300 or if you buy a stereo scope. The input lag is almost non existent, but it IS present...however, i can’t imagine anything short of a $400 digital scope really being much better. The the image quality is flawless, the screen, amazing, the zoom will focus clearly at ANY distance. it’s a sub $100 microscope, don’t expect the world...but if your expectations are reasonable, this will far exceed them. buy it, or spend the extra couple hundred to get what you really want because this is the best value for the price range! You won’t find better without dropping quite a bit more.
