If you own at least one trigger module, this pedal is a must. It's extra compact but very well built and sturdy, very accurate triggering. And for what you get, it's actually cheap.
I'm very picky about bass drum pedals, normally I play only Sonor Perfect Balance pedal and I was worried that I wouldn't be able to execute all the hybrid techniques I use quite a lot but actually it haven't been an issue. Sure, the playing feel is a bit unnatural because of the way it's constructed, but it's also rather sensitive and after a few days of adjusting it feels alright! It does slide away if you don't use the spikes. Maybe adding velcro to the underside is a good idea also but those two spikes are enough for me.
