I've taken some bashing for it, but I have had only good experiences with any bicycle-related items I purchased at WalMart, Target, K-Mart, etc.
Years ago, I ran a bicycle recycling program and I used to receive cases of brand new bike tubes from a certain bicycle manufacturer here on Long Island. They were all sealed in their original cartons, which were covered with Chinese writing. When I'd open the cases, I was always surprised to see that some were stamped "Schwinn," some were stamped "Bell," and some had no stamps on them at all. One thing that was clear, though (and the manufacturer confirmed this)... they were all exactly the same.
