irishthump, to be honest, no I hav'nt BUT the advertising suggests it makes it easier to master those fast kick patterns and to me, thats cheating. Now im slightly qualified to say this as my feet are pretty slow due to Arthritis in my anckles so I would be an ideal candidate BUT I would feel it was cheating at my craft.
Id rather play slow feet patters and it be ALL ME rather than have a peddle that allows me to skip the burn..
Anyway, its never a good thing to skip on technique.....there isnt many fast tracks in drumming, not at higher levels (im not pointing any fingers here

)
My opinions thats all..............
