I use this with my black/gothic band and made my drumming steadier and more effortless. I have it for a few months and see no play in the universal joint. Seems built like a tank and it's the fastest pedal I've used so far, hopefully will keep going without any play.
Previously had a direct drive yamaha, but this pedal is so much steadier, doesn't move, it's built to last like an iron cobra pedal.
Pros:
Steady, fast, longboard conversion, very little lag in the slave pedal
Cons:
For slower tempos type of music probably a chain driven would be better.
Played before on iron cobra and yamaha direct drive, and this is certainly faster then both and doesn't add movement when you slide your feet heavily unto it.
I highly recommend it for anyone who wants to play fast at a fracture of the cost of other machine cut pedals, hopefully it will last for many concerts.
