I have one, 3-12x, I quite like it. Sadly the deer didn't co-operate this year though. I liked the ability to record video, gps location tagged, etc. lots of other features I don't actively use, but fun to tinker with. The image is what it is, obviously not as clear as looking through traditional glass, but the low light performance is superior albeit a little grainy. The front focus takes a bit of getting used to, but once dialed in, it's easy to change focus based on different ranges. It also has a one shot zero, which worked surprisingly well. For the price I paid, I'm happy with it...
Cheers,
