I bought this bottle for days out walking and camping and after a few months of abuse being dropped it has lasted well without showing a mark. The strong design of the bottle allows it to stand up to any damage incurred and it's sleek design lets you pull it out of a rucksack with ease as opposed to one with friction of which i have found can sometimes be a challenge. The lid is also very strong with a tight lock and is easy to attach to any bag with anything because of it's large hole. A superb drinks bottle that does exactly what it's supposed to, 5 out of 5 from me.
