These are useless: I have no idea why I still have them. They either leak, the straw falls out regularly or the top is too big to drink from without drooling all over the place.
These are the kids' favourites for school. Laura's is too big and adds about 3 kg to her daily haul to school if I fill it up to the top. However, it seals well and locks to avoid soggy papers. Owen's is stainless steel and boy-proof. He is very attached to it and I had to buy two to avoid meltdowns if it should dare go missing. A bit of a leaker if he doesn't body-slam it shut, but largely acceptable.
This is my bottle. Oops, wrong photo....
This is mine, all mine. I do not share. Stainless, wide enough mouth to add ice cubes and good spout. Love it! Except I wish it was purple ... and self-cleaning... and made me better looking, but it will do.
Do you have a must-have water bottle? Is there a mug that is your favourite for your morning cup of coffee? Do share.
