Okay so I've always made fun of guys who buy these things. I thought "why would I pay money for something my hand can do for free?" Well, my friend convinced me to try his Ripple Pro last week and holy shit was I wrong. It's not even close. The texture, the suction, the way it warms up... it's a completely different experience. I came harder and faster than I ever have with my hand. I ordered my own the next day and it arrived yesterday. I've already used it 3 times. I feel like an idiot for waiting so long to try one.
