This binding machine may seem attractive because of its price. But just have it in hand to realize that this is a bad product. The leaves are first not cut correctly. The machine accepts a ridiculous number of sheets it irreparably shears. Everything is plastic. The format selection button seems ridiculously fragile. As I could not connect the leaves, I wanted to return the product and be careful! This product does not benefit from the Amazon recovery. This means that you will pay the BACK of shipping cost if the product does not suit you. And the icing on the cake, the seller is very, very bad faith. He returned the product for which I had asked for reimbursement by saying he did not understand my request and had exchanged. But he returned the same binding machine !! without even exchange it against another! And had to pay the shipping cost !! It is best to head to another product and especially avoid the seller who is a brand that sells everything with a very bad customer service.
