I play an electronic drumkit in a professional party band and was looking for some expansions cymbals for triggering splash and china sounds, rather than having them on rims/pads. This particular one caught my eye as it was specifically designed for it, so I bought this along with Triggera's 14" China Cymbal Pad.
Both pads are of basically the same build quality, hard rubber over metal. So they seem to be very hard wearing, but they do make more noisy than standard cymbal triggers. This is fine for what I use them for, but it may be noticable if used on a home kit. I did also find that if they weren't mounted tightly enough, they would sometimes mistrigger due to vibrations from the cymbal arm transmitting into the metal inner part. Other than that, I am very pleased. I didn't have to pay over the odds and they do exactly what I hoped.
