The Pulse Probe is a modern twist on a standard vibrator idea. The shaft is covered in wrinkles, but they aren't deep and can't really be felt during use. Even those who are sensitive tot exture should be able to use this without any issues. Pulse Probe doesn't have any seams, which is absoultely awesome. With the regular low to high vibrations modes that function by a dial control, this vibrator is completely waterproof. The vibes are a little buzzy, and they can't be felt that well in the G-spot bulb. However, for the price and safe materials, I think this would make a nice toy for anyone who is willing to try it.
