My device is the Precision brand. It has a rechargeable battery pack, and outer and inner device, and remote.

My husband jokes that when I am nagging he will just turn up the remote to shut me up - No offense please, it is all in GREAT humor.

How do this device differ from yours if you don't mind me asking?
