I've got the bottle since scarce 2 weeks and can say that they like it very much. It is lightweight, does not smell like plastic, plasticizers or the like and keeps absolutely tight. The color (I have orange) lights up beautifully and drink from it is fun.
The experience of other reviewers who described the the lids stained when using, I can agree with though, but the lid is nunmal rubberized, so the slight discoloration represent for me normal signs of use, which I can accept.
