I purchased the We-Vibe 4 and it has preformed with astounding results. I think the lady came close to passing out. It is the newest of the We-Vibe products and comes with a nice charging stand that closes up like a large egg. It also has a remote control device. This is the first vibrator that I have found that works while preforming intercourse. One pad works the clit while the other teases the G-spot. It has about three hours per charge but I don't believe a woman could tolerate more than a few minutes. I would be interested in any others that have any experience with it. The We-Vibe 4 is about 30% smaller that the previous models.
