Best I've found in half a century.
I've been wearing mascara almost every day for over 50 years, and this is far and away superior to any other mascara I have ever used. It absolutely doesn't clump. You can either keep building up layers until you can't believe they're your own lashes, or you can brush it on quickly and be off. The waterproof version is also good, though I don't care for the acid yellow tube color.
