I really like the No-Peep. I have used it for 5 years now and wouldn't use anything else-really great for low light shooting as you don't have to try to see thru a peep. With my bifoculs and aging eyes it really helps. Also it forces you to shoot exactly the same way every time. Any change in form shows up immediately. Broadheads-love them thunderhead 125's. Been around for a long time!
