Review: I purchased these to use as electronic drum triggers. They work great for that purpose. My only wish is that the wires were a little heavier gauge. The wires are very lightweight and a few of them came loose from the solder joints when installing them. Otherwise, a good price and they work as they should.
Review: I used it to replace the piezo in my electric kick drum pad (Alesis surge mesh head kick drum). The wire on the old one got worn out because the beater was hitting the sensor too much. I had to adjust the height so it don’t hit the piezo directly. You need to solder the wires.
