These are pretty great and come with a spectacular price. I mounted a 5-20x Nikon Monarch on my .308 with these. I've had no issue with scope movement after shooting or anything like that. They have a coating on the inside of the rings that grips to the scope without scratching it, which is a pretty cool feature.
Pros: Price, functionality, cool coating inside rings.
Cons: None that stand out.
