Review on 🌊 Foldable Water Bottle Collapsible: Portable, Leak-Proof Silicone Waterbottle 26oz - Medical Grade, BPA Free, Anti-Spill Valve by Dustin Barry

Good idea in theory. In execution. it doesn't quite work. I never use a water bottle as it easily tips over and loses its shape after you drink water from it. It has to be filled to keep its shape or you have to press a button to fill it with air, which seems pretty annoying every time. You also need to squeeze out the water, and when there isn't much water in the water bottle, it becomes more difficult and you have to fill it with air to be able to squeeze out the water, which is just troublesome. My regular water bottles are just simpler.
