Firstly I have never tried the real McCoy (Beauty blender) so I cannot make a comparison between the two, I don't think I will ever be able to spend £16 on a sponge but I have a cheaper version called the cosmopolitan beauty sponge.
I have never liked to use wedge sponges as I think they use up too much product but I love using this especially for heavier foundations.
It is a pain in the keister to wash though which is why I still have a teeny bit of foundation left on it.
How I use it
I damp it using warm water and it somehow makes my foundation give me the illusion of having AMAZING skin as it is almost impossible to get a cakey finish.
You can find the beauty blender sponge in Superdrug although there must be limited stock as I tried 7 stores with no luck but eventually found it in the Braehead store near Glasgow .
