I feel like the amount of brush from the bend is slightly shorter on this brush than other bent angled brushes I've seen. But for the most part, I feel like I can really control how I line my eyes with this brush. With my EcoTools, I felt like I wasn't controlling the precision of my line as well as the Elf brush.
