I recently bought the no peep and so far I like it. It isn' t " fun" to setup up, but insn' t really hard either. The newer ones have both vertical and horizontal micro adjustments, which makes this process a little faster. It is really helping me have more consistent form and best of all no more screwing with my peep sight. I like that I can shoot with both eyes open. With my old peep, sometimes I would see 2 sight appetures, and 6 pins (I only have 3 pins). I guess you could call this double vision. I think this was caused because I could see a little bit of the peep sight and I would some how focus on it. So far I am a happy with it.

P.S. I don' t know about the glasses part. I wear contacts.
