Bought this for my adventurous mate. Used it on a 6 hour drive. It (I) kept her entertained. She did not ask, "Are we there yet?" one time.I researched all of the vibrating panty options. Most had issues with poor quality of panties, poor vibration strength, battery failure, lack of or failure of remote control.She loved the different vibration / pulse settings. There was plenty of power, driving her through multiple "O's" during the trip.A week later, I went to pick her up for a short one hour drive. She asked me where her toy was.The remote worked perfectly. It restarts at the setting where it is turned off.The built in rechargeable batteries are much better than dealing with replacement batteries.Buy it for "her", neither of you will be disappointed.
