My 2cents,
Sounds like a little miscommunication/misunderstanding, I agree that his lipo tools may not be up to snuff for proper lipo care but it's not your fault. The 6s checks out Ok,eat the shipping and send it back and wash your hands of the matter. No ones getting taken advantage of except maybe you for the S&H charges but thats the price we all pay sometimes for bartering or buying used and wanting the transaction to be civilized and have contentment by both parties.
