Poor quality. looks great at first but doesn't last. - J5 Tactical V1 Pro Flashlight, 300 Lumens

I bought two of the J5 tactical flashlights a couple of months ago. One is kept in our motorhome and one is under the bar in our house. The one in the motorhome is still operable (I think) but the one that has just been sitting on a shelf either has a serious battery drain while it is turned off, or there is something wrong with the switch. I have installed 3 fresh batteries (it only takes one to operate) and within a day, the battery is dead. Won't take a chance on another J5 light.
