I love my Neuros!!
It is so easy to play my audio books now! There are five preset buttons
on the Neuros that can be set to basically bookmark anything. I'm
guessing most people use them to set favorite radio stations, but I'm
using one to bookmark my spot in my book. It's saved me a lot of
headache. All I have to do is remember to set it every now and then.
