I was very excited to try out the roller that wouldn't tangle with hair! However, since the first use, I've had to take the bottom off and remove hair that had tangled up in the belt and stopped the roller from spinning EACH AND EVERY TIME I USE IT. There are at least 10 screws that have to be removed or loosened to get the bottom off. Very time consuming and annoying. At least make the bottom plate easier to remove if you have to clear the belt every time.
