Holy cow, I'm using it on myself as I type this and boy oh boy. It bends to your contour and stays in place. Trying it standing up, bent over, rear up, squatting and won't move from the spot where you placed it, it definitely gives you a good reach. Underwater in the tub? Let me check....yep it's in there doing its job. 110% pleased that I made this purchase, your prostate will enjoy.
