Too expensive and doesn't work right away when I need it. However, it ended up working, so I decided to keep it. My main problem is that when I tried to focus this thing on the deer and when I got my footage, the deer had moved a few steps. Visibility is usually very cloudy, especially during low light periods. It's made of cheap glass that gives a matte finish. The ONLY reason I bought it was a misguided belief on my part that it would allow me to see deer at 1000 yards as accurately as my Leupold can at 500 yards. Not even close. I think you get what you pay for sums up this purchase. The return period has expired, otherwise I would have done this. Guilty!
