I love it and can’t find a single flaw! It shines on bass, guitar, synths, and even drum machines.
The specs are easy to find online, so I won’t go over them. Here are my 3 reasons to buy it... and keep it!

This octaver takes time to tame — it’s very sensitive to touch and your instrument’s output level. But that’s no reason to give up so quickly ;-)

What I want to highlight here:

The ringer: double octave and GAIN all the way. Perfect for waking up an overdrive that’s a bit too shy in a mix.
The tracking: I always leave it off, which creates "anomalies" and other "glitches" that are as surprising as they are delightful.

I was lucky to get €20 off, but even at full price it’s worth ten times that...
