Do you have documentation that you never received the tube tester? If so, it would seem that you have a case for shipping related damage (if the seller is not being dishonest). Was the package insured? If so I would suggest to the seller that you pursue a claim against the shipper. No reason you should take the fall for shipping damage or an unscrupulous seller.
I always require a tracking number and insurance on anything I buy or sell. And I am thinking of not only taking pictures of anything I sell before I ship, but also making a cell phone video showing that the item is working as advertised. Maybe buyers should ask this of sellers as well.
Having been burnt by shipping internationally, I also explicitly ask that any buyer who wants to forgo insurance adn tracking numbers to save on shipping accept all of the risk related to damage or non-delivery.
