I got this pedal for practice two years back, it being only $20 I didn't expect much. It has become my main dirt pedal ever since, beating out an TS9 and boss Overdrive
I run this pedal in front of a distortion pedal I use for all my gain. It does it's job of juicing my distortion for a tighter sound. (Using the Amp as an EQ, distortion for my gain.) Watch Fluff's video on youtube for some sounds. He compares it to a Maxon OD808 and it fairs well considering the $30 dollar price tag. I'd buy it again.
