I've used it for about half a year. There are no particular problems, but the name tag has been erased with a marker. It comes with a strap. Instant purchase is OK. Please understand that this is a used item that has been stored at home by a private seller and has been handled by someone else, and I would appreciate it if those who are not too concerned about minor details would purchase it. Please note that we may cancel the sale for those with significantly negative feedback.
