True. That's why I always buy the cheapest tubes, but only from Universal Cycles, Jenson USA, Bike Tires Direct, or any trustworthy bike parts distributor. I don't care about the heavier weight of cheap tubes, and their reliability has been at least equal to that of the tubes I've bought over the decades from Schwalbe, Continental, Michelin, etc.
