A rechargeable battery has a finite life, so to be able to use a toy for a greater number of years I chose a corded version for myself. I guess the Fairy Mini was my actual choice, though.
If you read the reviews, it says that the rechargeable one doesn't hold it's charge very long and that you would have to stop and switch toys to recharge it. I think either the original or the mini would be great buys
I bought the fairy wand massager on sale for $30 and I use it daily! It is the best for getting rid of cramps, stress/tension, aches and pains, stiffness etc and it's very discret also a amazing sex toy!
