I haven't had many problems with mine, but I would check the battery terminals if I were you. I've had to clean corrosion twice off of mine and I use regular Duracell rechargeables. I don't leave them in there longer than need be, but for some reason I've had corrosion issues. It was nothing major though, and the flash works fine.
