Quality is as expected of Pearl and works just as expected.
I use these with my Pearl Eliminator double pedal and mostly swap to one (I own two) on my main pedal when I need to play D-beat or blast-beats at extreme BPM's.
For me personally, the angle doesn't work very well when doing regular double kick runs or when playing at lower tempos - in those scenarios I prefer the red or purple cams.
If you have issues with consistency or high stamina drain when doing blast-beats or d-beat though, I'd recommend getting one of these to try out!
