I went in to buy this from the reviews I had seen and read. And I will say that it is good and I like the availability to switch from red to green dot. And overall the size of the tube I like it works for me. But, that being said Justin and I discussed the Tru Glo reflex and he was right about it not giving as much as the "spider effect" at some levels of brightness. And the TRU GLO has available IR built in, for about $ 20 less. But still happy with my purchase.
