Good. Its use was done on a perfectly clean chain which was cleaned with paraffin oil, toothbrush, and brush and dried with an air compressor (see also my review for C2). It lasts a little longer than the transparent C2, unless it's just my idea because its white color stays for a while and its content of Teflon deceives you. When you touch the chain after a while, you don't feel like you're touching real oil. It splatters less than C2 and splatters white spots, so it is very noticeable on dark or black rims. It cleans easily like C2. The splattering will last for about 100 kilometers at most, and it will be at its peak on the first ride. Its white color makes the chain look very bad. So if you don't care about the appearance of your chain, try it. I switched back to C2 and will keep C4 for my work scooter.
