These bottles are fantastic. The are a great size, holding just enough water for a day out without be excessively bulky. They are extremely strong and the screw cap seal never leaks no matter how much you knock it about! They look great too, and although it looks quite heavy it is surprisingly light when you pick it up.
I bought a cheaper 'copy' a few years ago but it rusted in a matter of months. I have had this bottle since 2009 and it is still in 'as new' condition. The water never tastes funny even after a day or too. I have used it for keeping a range of different drinks inside and the inside coating seems to cope no matter what.
This bottle is indestructible and i highly recommend it!
