To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is the best water bottle our messy 2 year old currently uses (and we have quite a few different varieties!). He loves trying to pour his water out and this bottle doesn't allow him to. It is true-to-word spillproof. With other brands he also tugs on the soft mouth piece to pull it out of the bottle and he is unable to do that with this either. It's survived quite a few drops and we just toss it in the dishwasher which cleans it nicely - haven't had dirt or mould build up in any crevices. Some of the images have started to peel off from the dishwashing but the vibrant blue of the bottle has lasted. Definitely would recommend :)
