Ok product
My BF got this one for me. To me it is an average product. The four adapters/heads do not really work well. I could not feel the difference much and vibration were diminished with head. They are also very easy to crack, then will not stay on anymore. I cracked 2 in first couple days. This vibe also seems has short life. However, it gets job done.<br />Prob: heads easy to crack, less vibration with head on, eat battery, does not last too long.<br />Good: small but enough power to get job done. Works very well without head.
