Edit: My battery is faulty (faulty contact) after a few months and only 2 or 3 uses. Despite several reminders, the seller did not even deign to answer. In addition, Amazon said he could not do anything and does not have the manufacturer's contact information. It remains for me to dispose of this product although it is always guaranteed. Damage to an item paid for at the time almost 15.
In short, be aware that you purchase a disposable product!
