I've used this brand before and it never clumped on me until I went to work. but that's also because I work in a deli so I'm constantly around grease and heat. On my days off I would wear it to do errands or just for a shopping day and it never one clumped up.
It's good. Use a primer and don't directly put the roller on your eye. Your eyes are sensitive so be careful. I always roll it on my hand then use a brush and build it up. Works better if you wet the brush a little
