I have one. It was on my HP standard rifle for a few months then spent the rest of the year on my SB.
It is light, focuses close, about the right power, has a smallish dot, tracks very well and is inexpensive. The odd number of clicks per revolution can be confusing, but once you get used to it and get your numbers you are OK. Only hassle with the 1/8" clicks is when you have a spotter who thinks in 1/4" clicks. Or when all your other rifles have 1/4" clicks.
It is sensitive to getting washed out when shooting toward the sun, but otherwise it is sharp and contrasty.
My only major complaint is that if you dont have your eye lined up just right you cant see anything through it. If you dont shoulder the rifle perfectly every time you have to hunt around like crazy to get your eye lined up. Most other shooters who have tried mine have voiced the same complaint. This can really kill you if you are not having a good day to start with.
For now it is working, but I plan to replace it with a Premier Leupold or that new Weaver just as soon as I hit the lottery.
