Hi Guest,
I used one and it was great - didn't want to have the storage nuisance of a permanent one ;) Guess how long it lasts for you is a bit like how long is a piece of string - will depend on your breed and how many and how active the puppies are I should think. Mine lasted until about 5 weeks by which time they'd started to peel off the layers but to be honest by then I would have been moving them out of it anyway.
Stayed fresh and clean no problem - base is coated with a sort of waxed film which prevents liquids soaking through if you change papers etc regularly (which I'm sure is your plan). It is a heck of a price for a cardboard box though. Teri :)
