Fuck, if there's a name or model number in that picture it must be really small, because I couldn't see it when I went to maximum zoom.
Usually when someone doesn't want to make it easy to buy something that they bought, it's either really good or really shitty. Which is it in this instance?
I have one of them and mine was called a MoKo WiFi USB Digital Microscope from that big online website. they have several models on there that look pretty much the same as the one I listed. A little lag when trying to take a photo to an iPhone/iPad but the picture quality can be stunning.
