The 2.0 hose is much better than the original 1.0. The 2.0 has a stronger gasket.
My issue: The first time I ordered my Kong their was no Indicator that said if it was a 1.0 or 2.0. This made it difficult to know what I needed to order for a back up. So far so good with durability. Great product, just add 1.0 or 2.0 to the containers and tubes.
