Everything seemed nickel unpacking. The saw is in a bag with all the equipment. Where it gets complicated is to install the blade. The screw is very hard to undo. Already well put the key into the hole to prevent skidding that damage the screw (a surfer had reported). You have to press the button on the side while pushing the key. A pain. Unfortunately, the screw broke. I have not even had the opportunity to try the device. Too bad. Device returned. Big disappointment.
