Sincere review here...
The water does not keep many cold hours as I imagined, after about 3 am it is fresh, but not cold.
Came with two knedges, as you can see in the image 4 the protective plastic was wilted on one side which caused these kneading.
The bottle does not sweat and does not leak, but also do not expect it to stay cold hours and hours, this does not occur.
