I've got one of the 4X T/C Scopes with the circle x. I put it on a Remington 1100 20 ga to shoot slugs. So far as I can tell it's a pretty good scope and is holding the zero pretty good. It's short and compact which I like but it's also 1/2" click at 100 yards which I'm not too crazy about. But the optics are clear. T/C probably has the best warranty in the business and stand behind it. I believe their scopes have the lifetime warranty same as their guns. I read a report on them somewhere that their scopes are just as good as the higher end scopes.
