If you shop at Sainsbury's you'll have met these things at the till they are bloody useless. The top comes open at the slightest touch spilling all the drink into the gym bag and even drinking through the top pop up bit causes the lid to pop open, and on the rare occasion that doesn't happen, you can't get drink out of the spout! .. we have two one each for DCs both complete crap. Its a charity so can't really take them back so bloody annoying.
So glad we had water in these and not blackcurrant. Sad too DD who is 4 was really upset that it was rubbish as she wanted to get one and had been asking after one.
