This water bottle is solidly built. It is perfect as a bike water bottle, since it is compatible with my bottle cage. After filling the bottle the bottle stays sturdy. It folds down easily and becomes very compact when you need to pack it away.

The cap works well. Works exactly as promised. It is always difficult to find a good compromise between quality and portability.

I like that it's handy and collapsible. I love how it inflates with a click of a button, making it suitable to be placed anywhere without collapsing for no mater how much water is still in there. Comes with a neat hook as an extra accessory.

The leakprook feature is great as well, been using this for days and everything works well. No leaks either. It is lighter than my other bottles and you can fold it when it starts to empty. It did not leak in my bag.

After a short time the plastic lining inside the bottle started to flake and leave particles in the water. All i can do is throw it out and it doesn't even look recyclable.
