Just stating my experience with them. Had two older Bushnell Trophy scopes. One was on a rifle that I bought used and the other given to me for free. Both were fogging internally and one wouldn't keep zero. I realize these are cheap scopes thus both have been replaced with better glass. Wanted to see how Bushnell handled lifetime warranty on a cheap scope. Got both back. They fixed a leak on one and purged it and sent me a brand new Trophy XLT for the other. Not a bad warranty for cheap scopes.
