My 8 year old uses the water bottle for school and has definitely been thru all you can imagine and the water bottle is still a live. The lid is removed very easily so you can re-fill and wash. This was one of my concerns because he needs to re-fill at school and some lids can be hard to open. He only flips the lid and the straw comes out no need to tilt to drink pretty efficient. Definitely it’s a great water bottle will be getting one for myself.
