Be wary
I didn't check the listing, but you might want to ask for additional pictures if they aren't included already. The gaskets that seal the bag cover to the fill tube and to the bag collar were made of rubber that dries and then chips off until nothing is left. When that happens, the system won't seal, and I have to tell you that I've never seen one of these uprights that doesn't have that problem at the age they've reached now.
