The Grit Stick is a very good idea, however, it is messy. When the top flips open, chalk goes everywhere. On the equipment and all over the floor. A chalk bucket is a much cleaner way to operate if you are doing crossfit and are in a hurry to apply the chalk during a metcon. It does apply the perfect amount of chalk to your hands, which is nice. I'm not sure if I will buy more chalk replacements for the GritStick. I have only used it a handful of times so far because it takes a lot of extra time at the end of class to clean the chalk off of everything. I will update my review when i have worked through an entire chalk container
