It's not very pretty or fancy like having a whole pedalboard set up for vocals, but it really does the job well!
Easy to use and set up without looking at instructions.
Overall very intuitive.
I originally bought a OBNE MAW, but traded it in for this as the unit was faulty. As nice as the MAW was, it was tedious to adjust around and chain up loads of effects and drag a whole pedalboard with other stuff with me.
This little blue brick basically does everything I wanted from a pedalboard, although without the funky features and very customized sounds a pedalboard can give you. But in return you don't have to tap-dance as much while trying to not screw up your live set.
It's been kicked around the rehersal space, and won't crash on me, so I am very satisfied.
Oh and the effects are decent, but not exactly top shelf, but I play in a Deathrock/Punk band, so no one cares XD
