I tried one in 3.5-14x40... it was great at 50yds, at 100yds, it showed its true colors. Blurry edges no matter what cheek position used, wouldnt focus to a good crisp image, eye relief at 14x was around 2 inches at best. I was very disappointed and promptly returned it and ordered a Vortex Viper 6.5-20x44 for a few dollars more. That was my first Nikon and it left a very bad taste in my mouth. Not sure I will buy another nikon, even the monarch, when I can get a Vortex for around the same amount. My 8 year old Leupold VX1 4-12×40 is a much better scope than the Prostaff 5.
Hope you have better luck with yours.
