Query: Nesco pressure cooker

do not recommend this item. Ist one arrived in pieces 2nd one would not work kept coming up with E4 on electronic screen. I called NESCO and they said it was a manufactures error code and would have to be returned. They said they did not know what it meant because the product is still too new. Maybe after they work out the bugs it would be better. Amazon has been great with the returns.
