Review on BlueFire Professional Flashlight Submarine Underwater by Mike Hernandez

I have two of these lights, bought the first one, has had no problems and has been with me on several dives. On the second one I bought the charger stopped working immediately after one use, the lights flashing like it's charging but not charging. Batteries used and charged on the charger of the first purchase, everything worked. Until I went to charge after the second dive and the batteries no longer hold a charge. The first set still works perfectly, but the second light, its charger and batteries are struggling.
