I don't use the rechargeable one. I use the one with replaceable batteries .. no cord. Reliefband Classic. I see the price has gone up .. my last one was 3-4 years ago. It is my second one. Usually at the bottom of the page Amazon will list similar items that probably work just as well at a lower price.

This is the official Amazon site for Reliefband. I think they have a regular store website they can be bought at.
