Love this product!

The S'well bottle is fantastic! It keeps my water cold - it actually does! The packaging says for 12 hours; I've never really timed it, but it does keep my water cold which is what I need to quench my thirst. It also works for keeping liquids warm, but I have yet to try it, though I'm sure it works as well. It comes in nifty designs - I have the wooden design. Would recommend this product!
