The concealer works really well and is very easy to use. For me, it didn't take many clicks for the concealer to slide out the tube, and when applying it, it went on easily and doesn't smudge. The only thing is that my skin tone is slightly lighter, so the concealer appeared slightly darker on my skin (but still looks great after blending it with the end). Also, after splashing my face with water and wiping it, the concealer still stayed on my face so it may be slightly waterproof (?).
