Bad experience. Arrogant sellers with very short demonstration without even being able to try the device. Cornering for purchase. Upon delivery, the packaging was destroyed by the appointees, so as not to allow me a possible recession since I did not use anything, if it was not cleaned (not recommended for those who have small rooms like mine) to finish the room started by the appointees themselves. SHAMEFUL!
