I recently purchased a refill kit from Cabela's for my auto inflator pfd they sold me.

when the refill arrived I look at the date on the pill it was already over a year old, and they recommend replace the pill every 4 years, called cabela's they said send it back i said no send me a replacement for your mistake and hung up...

to my surprise the brown truck delivered me a replacement today, I think that says a lot of Cabela's, I wasnt a big fan b4 but that went a long way
