those landmarks are crap in my opinion. the ones you got are not 150$. ive seen them for way way less. my 10x42s landmarks had water spots from condensation and are not phase correct but they are cheapos. burris is garbage to me and there customer service stinks by the responce i got. i would never buya burrris again. just to let you know those are imports and not backed by the company. do yourself a favor and get a leupold next time. transferable warranty for life and when you call them about a problem they pick up the phone.
