The device by itself is well designed, the tray is large (like a waste basket); the mechanism seems sturdy and is simple to implement. By cons I thought the cross was cut out very small pieces this gives 4mm wide strips of paper by 5 cm long; passing a check in the system and recovering all the pieces, with a little patience we come pretty easily to reconstruct the document. This is a good product but we must define what we want to do; for sensitive documents that does not seem to me sufficient as shredding.
