I know they have excellent customer service. I ordered a TV through their online store and had it delivered to the house. I watched in amazement out of my window as the FedEx guy tossed it onto the porch from five feet away. The screen was shattered. The local Costco returned my money with no issues. I can only hope they dealt with FedEx.

However it's not about returning them and getting some more. It's just annoying to have to do so. They aren't so expensive that I feel it worth the effort to return. I complain about too many other things.

The bad coin batteries just seem to come in cycles every 7 or so years no matter the brand whether expensive or cheap. Maybe it is counterfeiting as others suggest. Or just that the various places that actually make them for the brands that sell them just go through times of poor quality control.
