Title: Case of the slow replacement or perhaps no replacement
Review: The item was inoperative on arrival. On February 13, the seller gave me a return number and promised to send me a new tester. I immediately returned the item. On 3/5 I called to inquire and was told the item had been shipped; it had not. I made two more calls on 3/12 and 3/21; I am still waiting for the replacement.
