I've got the Vibrato and its great.....sonically anyway, very close (although not all the way) to my Boss VB-2.
Trouble is, they're built like a wet-cake, horrible plastic housing, rubbish switch that gives me no confidence at a gig.
So as a way of testing an effect, they're cool, but gigging? no, I'd rather run a metal housed/decent switch pedal.
