I hate changing batteries all the time; are any toys better than others in terms of battery life?
You might consider checking out a rechargable or plug-in vibe. The Hitachi Magic Wand is a big, powerful plug-in that also comes in a rechargeable option. For a tiny, hand-held toy try the Nea by Lelo or the Tango by We-Vibe: they're rechargable, silent, very pretty and has a wide variety of vibrations. And if you're looking for a toy to use with or without a partner, the We-vibe is a quiet, multi-fuction toy made of 100% silicone.
