Fast delivery. Congratulations Amazon. The device is easy to assembly. He swallows about 6-8 feuiles once. I did not go further because we feel it starts to hurt. There is no need to buy the recommended lubricating oil. The notice indicates that we can use a few drops of household vegetable oil. I put all the 2 bowls of shredded paper. I had a little doubt because there is a mark on the cover protecting the introduction of the paper slot (A4 only, not plasticized). However this reference is intended to be aligned with another feature of the apparatus body. When you toggle this cache more we reach a second line marked "off". Well at first mark the opening is very small. Finally I switched the cache on the second mark and the device still works! Apart from that I am very satisfied. Last point: the block is quite heavy and it should be removed regularly to empty the bin. I recommend buying.
