I've jad this for less than 24 hours and it doesn't work. - Streamlight TLR-6 Tactical LED Weapon Light for Springfield Hellcat

My tlr-6 just arrived yesterday. I opened the package and excitedly put it on my hellcat. Im not sure if there is a short in it somewhere or if it just came with bad or old batteries. I'm going to try and hooe its just the batteries because i really dont want to have to go through all the hassle of sending it back and waiting for another. So far im not happy with this purchase, unfortunately. At this time i cant say I recommend this product even though i know a bunch of people who love theirs....i might too it i had one that worked the way it should.
