Just when I thought it was safe to brag about this little guy....and I did too....this morning it just stopped firing. At first I thought it might be a low battery even though I was getting the right signal on the little led. Put in a fresh bat and it fired one time and died. Pulled the RM 2 and install the factory atty and it fired one time and died. This must be something simple. I will contact Kanger to see if this had been an issue for anyone else or if it just quits if the owner is a Cranky Old Man.....It worked flawless for one full week and was never dropped.
