Nice little light, really helps on low light conditions, solidly built, only con, I wish it had a more positive on/off feel.
Quality parts and speedy service!
Excellent add on to an all ready bright site. Perfect for early morning or late afternoon shooting.
Mine definitely has distinct notches for on/off and sight brightness. For me it is almost a necessity for the smallest diameter pin. The brightest level is way too bright- in fact even the two lower levels might be a bit brighter than I would like. Would rather have one that is "infinitely adjustable" as I would like just enough light to see the pin I'm using. But am happy with this and would recommend getting it to compliment the sight.
Works great makes my sight brighter in the ground blind.
