Joseph Joseph Dot Tracking Water Bottle 600ml 5 "Clicky water bottle is brilliant!" Miss Graves 21 May 2019 This is a fantastic water bottle. Every time you fill it up, you twist the green collar and another dot appears. It sounds silly but I find it hugely motivating - drink two bottlesworth in the morning, another two in the afternoon, then lo and behold, my body is hydrated. It's made such a difference, that simple act of making sure I've drunk enough each day. Hurray!
