The processing of the bottle and the closure is true - there is nothing to complain about even after prolonged use.
However, the 2 star trigger there because - with the price of the expectable life just do not quite match. I see these drinking bags not as a disposable product, but can it also not seen as a replacement for the water bottle years of use. I had been 4 of these bottles - sooner or later (with me really every day in use), the bottles discolor minimal inside. Even with very sorglichem handling and care is final with me and with very hard water after approximately 6-8 months. The discolouration can no longer get away - caused by everyday use, the water can never be 100% sure to dry in the very narrow tapered corners - so it's only a matter of time until a own microclimate.
I am of the idea itself excited, also tucking in tightly packed backpacks's easier for me - you have here really only the volume of water that you have to store, this is customizable in shape, better packable. If the bottle is empty, it falls well in terms of volume no longer significant.
Nevertheless, there are only 3 star - Camelback and Co are waiting here for a better internal coating and maintain over a long period of time.
