Review title: They leak
Product review: I have bought a set of different Bodum Canten Double wall glases, and within the first month of light use water has leaked inside the double wall through the silicon valve, so some of the glasses have steam inside, or are full of water. It looks dirty and I am not using those anymore. I have tried heating the glasses to see if the steam leak out and its still not good. I really love the glasses so I have contacted Bodum in order to get an answer on how to fix the problem
