What I have found is depending on where you purchase the sensors, you may be getting old stock that has been sitting on shelves for sometimes a year or more. I think that some of the sensors that end up on ebay and other online marketplaces at super great prices are, in fact, manufacturer or dealer old stock that has been part of a "stock rotation" and while they work fine when first installed, they don't end up lasting very long.
