Pearl PPS-20 Bass Drum Pedal Holder

I have to say that I am a bit disappointed in the Pearl PPS-20 Bass Drum Pedal Holder.
It basically works well, seems to be sturdy and holds at least my LP Li'l Ridge Rider Cowbell - which is a medium sized cowbell - reliably in place.
But unfortunately I could not manage to keep the holder from sliding out of position while playing. I think the two spikes that are supposed to keep it where you put it simply are a little bit too short. My hope is that a much thicker carpet might help with this but hadn't have an opportunity to try that out, yet.
In addition I could not prevent the whole thing from lifting up a bit when I fastened my Iron Cobra pedal to the holder.

To sum it up: I have not given up on this thing, yet, but am not using it at the moment. I recommend checking it out first with your pedal and comparing it - for example - to the LP product of similar design - which I wish I had done ;-)
