Query: Didn't last very long

I really like shaved and crushed ice, so I bought my Deni 6000 and started using it 1-2 times daily. I was perfectly happy with the ice that came out of the machine, but it did bounce around the counter while operating. The main problem was that after only a couple of weeks one of the metal shaving blades broke off, and this turned out not to be repairable. So, I was happy with the thing for a short period of time, but it didn't last long.
