The BGee requires 2 AAA batteries and has 6 basic vibrating functions: steady vibe, a strong steady vibe, extra strong steady vibe, pulsating vibe, rollercoaster vibe, and the other two being a variation of the other four vibe functions. Depending on one's mood, each intensity level escalates from strong to extremely strong. I personally didn't find the vibrations as strong as I'd hoped. I felt that most of the power was located more in the base; I didn't find that the vibrations were that strong throughout the shaft and the tip. However, despite the vibrations not being as strong as they potentially could have been, the BGee Deluxe still did the trick at stimulating all the right areas and places. The noise level was delightfully light, like a loud humming sound. The greatest quality of this vibe is that it is waterproof! It functions perfectly in water, be it during a shower or in a bath.
