The 5"/13cm PowerBullet Breeze, complete with our soft touch feel, is our newest product, one that we are most proud of here at BMS. No other vibrator has this much power for its size. - Operating on two "AAA" batteries, our testing showed will last 6 hours nonstop vibrating on high speed, and 12 hours on low speed; amazing power and durability for such a slim classy product. It's so well designed, that when it's operating on high speed, all you hear is quiet vibration and power. To compliment this beautiful product even more, it's priced right!
