I debated whether I should splurge and spend $20 on a tiny sponge but let me tell ya, I'm glad I did. I've never been a fan of using a brush to apply foundation because it takes forever, leaves brush strokes / looks cakey, and seems to waste a lot of the product. This sponge makes it SO easy to apply foundation and somehow manages to give you a flawless finish yet look like you have no makeup on. It's amazing, you can apply 100 layers of foundation if you want and it still won't look cakey, annnnd it takes me barely a minute to apply to my entire face. It is really pricey, especially considering they recommend buying a new one every 3 months and they say you "must" wash it with their specific cleanser that costs another $18... I'm definitely not going to do that.
My only complaint is that it leaked purple everywhere when I washed it the first time and was hard to remove the stains from my sink. Not sure if the pink one has the same issue or if they warn you about this, but regardless, it was not fun. But whatever!! The sponge still gets 5 stars cause it's bomb.
