Things I liked: Great, solid feel. You cannot beat it for the price. Flip up covers flip up great. Dots are really bright compared to other manufaturers within this price range.
Things I would have changed: Battery cap feels cheap and I got the one that has "Leapers" labeled on it, not the one pictured, but I'm just nitpicking.
What others should know: I really have no reason to change anything. I got exactly what I was looking for. I don't care too much for magnification being that I purchased this for CQC airsofting.
