I like it!
My non-rechargeable battery driven Emjoi broke so I debated whether to order the corded or the rechargeable version.  I am glad I chose the rechargeable version.  I charged it for the full 16 hours as per the directions and it runs fast and efficiently and has not slowed down during its use.  I cannot speak to it's longevity since I have only had it a few days. If you are considering the non-rechargeable battery driven version, understand that it goes though batteries fast and that costs $. While I cannot compare it to the corded version since I've never had one, I think that the rechargeable one was a good choice.  I use it every day since I am one of those everyday sandals kind of person and the skin builds up fast on the heels.
