Had a very good experience with customer service at the Aerobed company.
After using my Aerobed queen bed occasionally over several years, I was disappointed to find that the plastic tab on the air valve had broken - and that the mattress would not hold air. Annoyed with the thought that I'd have to get a new bed just to deal with a stupid piece of plastic, I did a web search and found a review of someone who'd gotten a replacement valve from the company - just for writing.
And I've just done the same. If you use their website (Customer Service heading) to place the order, all you do is send in the model number of the pump and they send you a replacement valve, for free. Why they don't even charge shipping & handling, I don't know, but I'll take it. The directions for replacement are in .pdf form on the website, and I understand it's a straightforward. (I'll post back if not.)
Nice after-service, congratulations on knowing how to run a company.
