Rimmel London Stay Matte Mousse Foundation

I've seen hundreds of adverts for this foundation in so many magazines lately. It seems to be really popular yet nobody I know has tried it so I thought that I'd be the first.
At 5.99 it's already cheaper than my 7.99 foundation that I regularly buy. When I got home I put it on straight away. It's a bit thicker than I'm used to as I prefer liquid to mousse foundations.
