Use: I play this with guitar electric or acoustic, so far, just at home.
The sound quality is really nice (I don't know about loud PA systems...). The effect knob is a standard rotary knob without any clicking. The settings are quite intuitive when going from effect to effect, they are the same, so it's not programmable, which is fine to me.
With the delay, usually a minimum time would mean a 'single repeat' but this is not happening here, so it wouldn't be your best 'slapback' rockabilly pedal.
The flanger is the only other questionable effect as it is difficult to get a middle of the road flange, it is either a little soft, or a little extreme.
All in all a brilliant pedal and not just for the price, for the sheer functionality to sounds ratio and no messing around with programming, just plug and play.
I didn't test battery life, so I don't know how that would go.
multiple usable effects
Easy to use
Not what you would ask for from every effect
Plastic Build(hence the price)
Overall: Has it has it's own character and I would buy the same thing in a steel enclosure if this broke and that were available.
Dirt cheap multi fx with high quality sound. If you want to experiment with pedal fx on a budget, this is a great pedal.
Although, not a perfect example of all effects, definitely creatively a pretty expansive sonic palette to experiment with.
