I bought this bottle, because I did not want to drink forever from old PET bottles. The design is very nice and even has a unitspan, so you can check well how much you drink. As might be expected, it is of course heavier than a PET bottle and therefore it is more exhausting, she in her handbag rumzutragen example with itself. You must be flushed through the large opening easily by hand. What I do not like so much the material of the cover. He touches his good though, and is easy to set up and turn off, but he acts quickly dirty and attracts lint and crumbs on. I would next time to buy myself prefer a smaller bottle (500 ml), so that it is handier and lighter.
