Just bought one. I liked the peep but I was losing too much light during magic hour and couldn't get a good focus on the pins. The No-Peep takes some fine tuning but once it's dialed in, I find it to be quite natural. I don't constantly look back-and-forth, as some have warned. But I use a Trophy Ridge with a level, so I'm used to adjusting with peripheral vision. I've got an elk hunt planned for September and I'm looking forward to using it in dark timber.
