Only read about them a bit but the sight looks good and from a reputable company. Wide field of view. My only concern is the auto wake up feature. The sight goes to sleep and wakes up when moved. Dont know how much movement required or if there is an override. But I could see a bird come in with the sight having gone to sleep sitting on my knee and the little movement needed to get the shot off maybe not waking the sight up. Don't know if it is a problem or not, just a concern I thought of while reading.
