I had one of their sights (not that particular one). Before I wrote this I went looking for it on their web-site - and couldn't find my particular sight. I think it's an older one they may not make anymore. In any event, it didn't impress me. It's one of a number of sights I went through in fairly short order looking for one that really suited me. I can't put my finger on anything in particular that disappointed me, but it just wasn't working for me.
I very quickly replaced it with a Lucid HD7 Gen III - which I like a great deal better. That one will do until I can afford what I really want - an ACOG.
