I charged cleaned and filed the device, then pushed the minuscule button to test it and indeed it started to spray water after applying enough pressure long enough. However using it “in situ” was a challenge. Even a little bit of water made the lexan plastic reservoir impossible to hold. while the silicone nozzle was more comfortable, once in place finding the switch was a challenge. Trying to press it with lube covered finger was no easier was like squeezing a giant watermelon seed through your thumb and finger. I was never able to turn it on while actually using for the purpose ti was “designed” for. Maybe if you have extra long arms… and of course as usual, no refunds. Impossible to hold, impossible to switch on, impossible to use, save your money, you won’t be able to get it back
