A week after receiving the grinder, I used it several times, about an hour in total. I'm careful with my tools but have found the dust box is cracked and spewing dust everywhere. Also, I'm having trouble finding the part on the Bosch website. The website lists the canister as a grinder. The # part contains spaces, but the search function could not find the # part with spaces. Bosch charges $70.68 per can including shipping and taxes. I used to buy mostly Milwaukee tools but found that they don't support parts for their tools. I was hoping for a better Bosch experience. Otherwise, an expensive grinder works just fine.
