The control window is useful for monitoring the filling of the basket and prevent the jam; the tray large enough, however, is quickly filled! In case of continuous operation, it takes a good ten minutes between trash dump for the shredder cool and agrees to restart. Do not forget to regularly lubricate the insertion slot (From the kitchen vegetable oil is enough!) Great buy!
