I find the glass to be very clear, bright and focused/crisp overall. The one area that I can say I've found an issue with is at max (25x) magnification. Everything gets a little crazy there, eyebox becomes very tight, mirage come on strong/blurry, very easy to move my head slightly and have a parallax issue with blur or shot hitting slightly off of POA. If I dial back just a tad, 2-3x'ish everything comes back together and looks great again. For me moving forward in the very few instances that I dial way up I'm going to use this scope as a 22x. I'll continue to try to see if I can find the magic parallax adjustment to make 25x usable. More time behind this scope will probably help a bunch.
