Customer service originally responded to me, but when the problem was determined to be the charger cord…. They never replaced it. Aside from that; I find the auto-off feature more of a PITA than a convenience.
Compact discrete long battery life
Screws in...not magnetic...have to push 5 times to turn it on so less chance of burning up the cartridge while it's in your pocket. It shuts off after 5 minutes.
Very portable and easy to carry
