Pro tip: always check the battery date on a new-in-box sensor before you mount it, even if the box is sealed

I just had to redo a whole apartment install in Tempe because a brand new door contact from a batch I bought two weeks ago was DOA, which wasted a Friday afternoon and made me look bad in front of the client... what's the weirdest 'new' part failure you've run into?

Check the batch number, not the date.
