Love 'em. Use 'em. Got a new pack of them along with a bow stabilizer mount with build in LED. The LED is acutually red light which shows up well and doesn't spook the wardens....I mean animals as much. It even has strobe setting if I really want to make it more blinding. I first used this set up over at a feed station I found. Pretty cool, they put out tons of hay and stuff for deer. Must be good feed because it makes them grow big as a horse with crazy antlers. Using the lights "narrrow beam" function I was able to take some pot shots from about 100 yards out. I know at least a few arrows hit because some of the deer ran off. I found one and got some real good meat off. I think it was about 20 lbs. I had to leave the rest because that was all I could fit in my fanny pack.
