Good, but not as great as I'd hoped. Information I read made it sound like it would bring about climax at a faster rate. I did not find this to be the case for me. Still a fun toy, just not as amazing as I'd hoped.
Holy Toledo! My wife has used this twice in the past 4 days since delivery in my presence. Did she orgasm within a minute? No. The first time she was nowhere close to being turned on, the second time I wouldn't let her orgasm as quickly as she could have. Both times she was writhing before climaxing and shaking after.
This thing is easily my best toy, if not best purchase ever. Currently my best friend. I just got finished using it for the first time and my entire body feels like snow on the tv screen. It was tough to get it to turn on at first. It has to charge for longer than you think before it's ready to go. On the lowest setting, it's great for getting warmed up. Once it gets going, though...wow! You know that feeling when you're getting bomb head and you're just like "I surrender to the fact that I have no control in this situation. This person could ask me for my life savings and I'd happily hand it over"? That's how it feels. I was stuck lying on my back, legs shaking, for a minute afterwards. That--and the fact that I couldn't stay quiet (I have 3 roommates)--would be my only foreseeable downside
