I was so pleased with the price and quality of these batteries. The shipping was quick also. When my son see his z-vibe and realized that it was working again his face lit up with a giant smile
Please note: to turn the unit on, twist the switch tip in *just* until it starts to vibrate. Any further will not increase the vibration, but significant over-tightening (although hard to do), may damage the motor.
Caution: contains small parts that may pose a choking hazard. Please handle with care.
