I wish I could get my money back but the window is now closed as of a week ago! I am not sure why they stick to the paint on the door where I have it hanging. The battery life is good for being rechargeable, it will go into power saving mode after a certain period of inactivity. They look nice, but thats about it. Does that mean this little box isnt worth it? Not at all! I never put anything smaller than an elephant in my ears, per my doctor?s orders. They are always right on with size. Battery life is WOW! So I dont expect to need more. I was pleasantly surprised that I received these sandals so quickly.
