Review Summary
The reviewer has been using the Klean Kanteen 40 oz widemouth water bottle for two years, which has been well-used and has a few dents, but has held up well overall. He uses the bottle to store water and to cook over a fire, and mentions that it does get discolored from the heat but that most of the discoloration can be cleaned off. He also mentions that the plastic top of the bottle can melt if it is placed on a hot surface, and that his friend had to replace the cap because of this. The reviewer notes that the bottle has a good seal and does not leak, and that it can be used to keep water warm at night by sealing it well and placing it in a sleeping bag. He mentions that he would definitely buy the bottle again, despite the issue with the plastic top. He suggests being careful where the bottle is placed around a campfire to avoid melting the cap, and mentions that he is not aware of any stainless steel water bottles with a metal top.
