This is a good size bottle that hasn't leaked. It is, however, starting to gain quite a lot of aluminium oxide deposits on the inside. The description said it was 100% steel, but it isn't.Second bottle I have had, the other was a bit dinted. Use it for dogs water when walking, keeps it cool. Happy with product.Well made, but has developed an unpleasant artificial smell that cannot be removed. Disappointing.Sturdy good quality, bought for d of e for daughter only thing was I should have bought a bigger oneSturdy non leak - metal taste takes a while to wash out
