Now that I' ve had some time with my No Peep, it was a VERY GOOD investment.

The only problem I had was that I have never shanged my anchor point from my old Instinctive tab shooting days [appache style-three fingers under]. I am Right Eye Dominant and have always aimed that way. Wiuth No Peep it gives me a better sight picture when I aim withe my left eye.

I am very well pleased and recommend it. BTW my glasses have presented NO problem at all.
