> 3 dayThis is a good product, this price was better than what Schaeffer direct offered. To get better, my order would have to be a lot bigger. The convenience of delivery was helpful. At one time there was much less costly Chinese alternative but no longer available and it didnt have the ratings CK that this purchase offered.
