Battery life is short; and there's an amazing reason for that. I remember when this toy first came out. It was on sale for about $55! I thought, wow that's pricey but after I was shown the demo models of what this baby is capable of and trust me, this ring is a MUST have. If you love to please your woman, this makes the perfect clit stimulating ring. The vibrations have different channels/intensities and believe me, you can make the bull go mad (which is why the battery life gets drained really fast). All in all, I would just recommend buying some extra batteries to go along with this purchase.
