Love this water bottle! -no leaking (so far) -keeps ice cold Or hot very well -provides useful instructions (do not fill with boiling water) -really useful shape fits easily in small space -fits in gym machine holders -holds good amount 500ml I previously had a Chilly style bottle, it leaked, the shape was annoying, the pattern chipped off. The shape and design of this bottle is so much better. The opening is wider which is useful for tea or a slice of lemon. The rubber round the lid means it doesn’t leak. The rubber around the outside is great for grip and holders.

I like my protein shakes cold and I don't drink them fast so I like using double wall bottles for my shakes. The drink does stay cold which is why I got it 2 stars but the mouth is not big enough for my protein scoop so protein just gets everywhere.
