Overall, an amazing pedal with very solid construction and absolutely accurate response.
Coming from chain pedals, the direct drive was a big difference for me. However, after a few minutes adapting to it I could already play solidly at much higher speeds that with my old Millenium PD-222.
However, it has two major flaws that did not work well with my setup.
First, the slave pedal has no spikes below or anything to attach it to the rugs other than some adhesive Velcro straps. And these would not stick to the type of rugs that I use, so I had to put something else in front of the pedal to hold it pedal in place.
Second, and most important, the two maces are very off-center. The right mace hits the bass drum right in the middle, but the left one hits about 5 inches to the side. I guess that this would not be a problem in a 22 or 24 inches bassdrum, but for my 20 inches one, the sound and rebound difference was just too much.
Sadly, I ended up returning it to get another one with spikes and centered maces.
