Love my RnB! Got mine around Christmas and have 50+ hours on it so far. I have charged it up twice during that time but never have let it get below 2 bars, I guess old habits die hard. I like the fact you can charge it up anytime as it has no memory, kind of like filling up your gas tank before a long drive. I don't even bother carrying spare AA's anymore as I can do a few 5 hour hunts and only lose 1 bar during all that time. It's a little spendy to purchase but I just cashed in a few months of clad to get mine. Hope it lasts a few years, don't ever want to go back to the AA's. Good luck!
