Boxwave Anti-Glare Screen

[BfA]

I was wondering if anyone can comment on the Boxwave Anti-Glare shield? Does it make a difference versus bodyguardz or IS? Or is it no different from their regular screen? It doesn't cost anymore so I'm skeptical of the difference it could make as I'm not sure why they wouldn't have just one model then?

I was thinking of getting the anti-glare for the screen and something else for the body. This is the one I'm talking about:

Just looking for comments from anyone who's used it or from anyone who can say whether the anti-glare works or not. Thanks!
