Pretty weak specs compared to a "real" scope, but it's pretty decent as far as pocket scopes go even at prices several times that. Looks useful if you just need "a scope", and the price is hard to beat.
I'd have liked to see a multi-channel (16 or 32) logic analyzer input, too. That's usually pretty doable if you're willing to disable the analog ports while using the logic inputs. But again, $200 is cheap for this kind of thing.
Looks like a Chinese "hey we make stuff" type outfit (note the Engrish). I've had mixed luck with such places. Sometimes you get something very good for the price. Other times, you get something that goes straight into the garbage can. Dunno what to say. I do appreciate the open-source nod, though I don't see any actual source or docs.
