Caveat Emptor.
Walter's Core Power Diamond Xtreme cable 15amp was cheap and useless.
He made a wildly hyped-up 90% - 95% performance comparison guess to Nordost's Valhalla 2 power cable. He refused a refund and grasped for store credit less 15% restocking fee. PayPal independently heard us and quickly fully refunded me.
Walter then falsely claimed to Audiogon he'd won an appeal with PayPal. He sent Audiogon a supposed PayPal logo'd appeal confirmation, but oops, he had the wrong transaction number.
Audiogon chose to delete polite negative feedback, despite an offer for a live 3-way call to PayPal and the proof of three PayPal account screenshot photos. One might possibly ask is the main priority to keep sales rolling unhindered by the truth of a customer's experience?
Caveat Emptor.
