Wait, 2.1 million records in one night with just auth and scoping in place? That is terrifying and honestly makes me feel dumb for never testing my own limits with a real load script. I always assumed a leaked key would get caught by scoping, but clearly that is not enough if nobody is watching the request volume. Going to go check my per key limits this week.

I was in the same boat, figured the shroud was just another gadget to part me from my money. Cutting a trench in my garage slab changed my tune real quick, the dust went from "can't breathe, can't see" to barely anything floating up. The fit is what makes or breaks it though. A loose shroud on a cheap grinder lets dust shoot right past the edges, so you end up with half the mess and none of the benefit. Spend the money on one that clamps down tight on your specific grinder model, the $30 ones can work fine if they actually seal up.
