Got this for my son's school functions. Got a chance to use it this past weekend. We gave out free shaved ice and kids were coming back for 2nds, 3rds, and 4ths. We worked nonstop for an hour or so, went through 3 bags of ice and it didn't hiccup once. Don't put the cups to close to the spout or it will clog, but other than that it worked great. The only gripe I have is the course adjustment knob doesn't have any markings to tell what you're set at, but if you leave it set at one adjustment then you'll be ok.
