I like the Sentry scope but it broke the second day that I had it. You twist the eyepiece to change magnification which is stiff. They eyepiece broke free of the magnification ring so I couldn't chang the magnification without pushing the eyepiece with force against the magnification ring. I sent it back for repair.
Pros: Compact, magnification range, camo, light weight
Cons: broke on day #2
