Oh, that looks like the Bass Bio-Flex brush I considered getting! The Bio-Flex comes in Swirl (which is like the one you linked) and Leaf, and I got the Leaf because it looked sturdier. I've only used it right after showering and right after taking out my still-damp sleep braid, but I really like it for those purposes. The wooden brush I got is also by Bass; it's the Green Brush.
