Query: Don't waste your money

If you like to save time and money, forget about this terrible grinder. It just doesn't work!! I spend 30 mins and just get 10 oz grinded meat because meat doesn't come out. They all stucked in the machine. Something must be wrong with blades. However, they are new. Initially, I thought I didn't know how to use it correctly, however, after a try by an expert, he also gave up and suggested me throw it away.
