You've watched the video but have you read the reviews? The very same review that had the video says this in the Experience section: "I had the best wank in the world with this cup. I never wanted it to end. Despite the fact that the onacups are meant to be disposable, I was really hoping I could get a little more life out of it. I tried to wash it out so I could use it again, but it filled with water in all sorts of strange places and I couldn't drain it and had to throw it out." Judging by that, I'd say it's only really good for one use.
Also, I thought you might appreciate it if I pointed out that there are specific forums for the topics on which you want to create threads. You put this in the "Vibrator" forum but the Air Cushion Cup is not a vibrator. It is a masturbator and should have gone in the "Masturbators" section. Hope that helps!
