Ok, back to the standard answer
I've hunted for over 40 years. If the scope doesn't say "fog proof/waterproof" it isn't. If you're target shooting that's one thing. If you're after the buck of a lifetime (as I was) and had the cheap scope fog up during rainy weather (like I did) you wouldn't be so quick to get one
I had a Simmons scope. Wouldn't take another one free. Wouldn't hold zero, fogged up when I saw the 14 point 29 inch spread buck that I had been after for 4 years.
IMO, cheap scopes (Simmons, Atec, Tasco) aren't worth the trouble it takes to mount them.
If you absolutely have to stay low priced, get a fixed Bushnell 4x. Used one for years on my 12 gauge with 3" slugs. Never fogged, never lost zero.
Variables have a lot of moving parts inside that can let in moisture and move around to lose zero. One way to test is to change power settings. If it moves easily, it's loose and and pretty much junk.
Buy good, cry once. Buy crap, and you'll just keep on buying.
