I've owned this pedal for a few years now, and it's a great little pedal when you put it into the proper context. No, it's not the harmonization you see from it's big brothers, but it does track vocals very well, and gives you exactly what you ask for. It can be used, without sounding too cheesy, in a lead vocalist equation if you blend the wet and dry signals properly. Where it really shines, however, is taking your backing vocals and adding harmonies to them. The bands I have played in found this to be a very good way to get around having only one real backing vocalist.
One thing to note, however, is that onstage volume bleeding into your mic can make the harmonies jump, so if you're right next to a drummer whose cymbals are ridiculously loud (like mine have been), you either need to gate it ALOT, or go without it. But I've found it's a great little pedal that definitely helps fill the harmonies when used with its strengths in mind.
