The Flanger works and sounds amazing. The delay has almost no effect and may not be working. I did some checking online and it seems to be a common problem with these so it maybe just how the pedal was made but please be advised the pedal doesn't really have any delay sound.
The pedal shows cosmetic wear and also has some holes in the side, the reason for I don't know, it was like that when I got it.
