I’ve tried others and they don’t compare. I prefer this one over all others. 

I had the original pink one and then I got the Pro. Somehow, the sponge fills slightly different, but both cases have a very nice quality sponge that doesn't turn into mush when you add the water, like some more affordable brands I've used.

This does objectively work better than the dupes. But, I went to wash it and before I got all the foundation out, the top broke off.  I could see there was still foundation inside the pores of the sponge, so I don't know how to keep them hygienic, and they are too expensive to be replacing every fortnight.

I have tried the 'dupes' for this but this is the original for a reason.

Tried other brands and this one has the best quality.
