Query: Would be great - if it worked more than 10% of the time. Found a fix!

Great idea, even a great design - but obviously poorly manufactured. The battery connections are miserable and the darned thing just doesn't work most of the time. Pretty useless if it's not dependable and you spend have the time messing with the battery cover. Didn't save the pkg, so I can't send it back... but I have put Neiko on my no buy list.updated review - we put a 1/8" flat washer in the "head" area of the flashlight just before dropping in the battery pack. It sits in the little area where the pointy end of the battery pack goes. It makes contact all the time now where it needs to. All of ours have worked just fine since we did this.
