I've had one for months, got to shoot the 270 Ultra it's on but had gun problems(see 270AI in H&R forum) and haven't really got to shoot with it enough to test it, for what little it's been used getting on paper, it seems to work fine, glass is very clear and bright, at least as good as any of the Leupold VXIs I have, eye relief is good, but the leupy is less critical with a larger eye box, but costs a fair bit more too.
