Review on Klean Kanteen Insulated Stainless 2 0 20Oz by Kelsey Brown

The bottle is beautiful. The lid is leaking. The problem lies less in the design than in the material. The rubber seal is too hard, you cannot fully tighten the nut. I overtightened it so that the plastic collar between the nut and the gasket wraps around the stem to keep it from leaking. This would eventually deprive the stock. Edit 12/14/17. The top of the ridge (the concave side, the center, not the outside edge) of the part that will clip onto the rubber grommet. I removed it with my dremel. Still no evidence of a leak, but instead of a small jet, only a drop comes out when we turn it over.
