I have never been a big user of vibration but this little dynamo may have made a believer out of me. At such a low price I decided to take a chance and am glad I did. Three speeds with the highest being teethchattering in strength, and a well placed bulb gave me a super strong orgasm when I wasn't even really in the mood, which I think is impressive. After all, it's much easier to have an orgasm if you are already aroused than if you are just going through the motions mechanically, which is what I was doing. I decided to just try it out when it arrived and it left me weak in the knees and feeling rubbery. Great bang for your buck!
