IDK if anyone here uses them, but I have SEVEN. I got an email that 10 reports have been made about malfunctioning batteries that could cause a fire or injury. It's too bad I am not a liar in this case. They'd refund me $140 if I said I paid full price for all of them, but I got 5 of them with $1 coupons, which I was honest about.

Anyway, if you do have one or someone you know does, we are supposed to not only refrain from charging them, but any that are charged should be disconnected from the cartridge and put aside. Even just leaving them ready to fuel the cartridge is apparently a possible danger.

They said to cease using the products immediately.
