Review (3/5): Do not last long
I have never used a true Beauty Blender so I cannot compare this product to those, but I have used a few different brands of Beauty Blender dupes, and these are my least favorite. My first and biggest complaint is that these sponges do NOT last long. They rip very easily. All of the sponges I've owned have eventually developed tears, but not nearly as quickly as these, and not as severely as these. The rips are deep and the sponge pretty much splits in half, other sponges I could still get away with using for a little while when they developed tears.
The other issue I have with these is the texture and consistency. The two pink sponges for some reason seemed to have a softer/smoother texture than the black ones, and gave a much better result.
Unfortunately, even thought these work okay, I would not recommend these sponges simply because you can get better ones at the same price point.
