Not a toy. It really helps your voice and your confidence.
I can't find a thing I dislike. It works exactly as I expected: it has a nice range of reverbs, the corrector is very mild but highly effective and the tone turns my donald duck-like voice in something else I too can bear to listen to.

Your voice supported
I bought this through my better half's account and tried it twice. Happy enough though not sure about the value: it feels expensive for the job, but everything they advertise it for, it does. Nice reverb and the tone is extremely helpful. The actual duplicator i like better on tight, but you can choose. Really not sure why they added the octaves: to me it makes no sense.

OK for the price
Not as good as the more expensive models - such as Helicon GTX but you get what you pay for. It also needs the power supply, as batteries don't last long. It also turned off midway through a song one one occasion

Easy to use
sounds good and easy to use worth the money works good even with a cheap mike

Doesn't work even with 48v phantom power
Tried it with several mics. No signal, battery powered or plugged into the wall. Defective unit?

Footswitch not working rendering it useless..

El botón del tono hace que acople bastante y refuerza los agudos y “esses” pero para mal en ese sentido, la corrección funciona bien , no hay duplicado de voz bonito y la reverb tampoco me convence ..
