Ring yourself and put your phone in your hand to test the strength of your phone's vibrations. VibraSMS are shaped to conduct the vibrations from your phone as strongly as possible. Remember that the area VibraSMS is designed for is more sensitive than other bodyparts!

See girls using them! (adults only!)
