I bought a Bushnell Sentry 18-36X50 spotting scope last week. And the first time I turned it up to 36 power one of the lenses inside fell out of place.Yes I was Quite pissed off to say the least.When you pay $100 for something you dont expect it to break the first time you put your eye to it.Im going to replace it with a yukon, Ill let you know how that turns out,
