Hello everyone, thanking you for the interest shown in our items on offer, we would like to point out that as private sellers, we also sell objects from third parties, therefore the objects on sale are tested to a minimum, even functioning perfectly despite the wear and tear of time, this It is the reason for the sale as defective parts. We are at your disposal for information on the product, to overcome the small difficulties that you may encounter when purchasing used items, our regular buyers are technically able to resolve small difficulties in use and have demonstrated this to us with positive feedback, but if you are looking for an item with guarantees we recommend purchasing a new item. Thank you for your interest in our items on offer. Happy shopping on recycling_b-linee
