I always use Chanel mascara base. My usual one was out of stock, so I found this one and bought it. It turned out great. The ingredients seem good, and it's moisturizing without being too thick, which I like. It also seems to have a large capacity. I don't really like the design, but it's easy to open and close, and easy to apply. It doesn't clump or become brittle. It's fiber-free and gentle on the lashes, and the finish is beautiful! However, it doesn't seem to come off with hot water.
