These bottles are great. We wanted them for traveling and unsure of the water. They work great and keep the water at room cool. Keep in mind the filter does take up a some space.

It makes tap water taste better and keeps water cold for hours. It DOES NOT leak!

It's very hard to drink out of, the suction power it takes to pull water through the straw is too much. You run out of breath before getting a sip of water. It does not change the taste of the water at all, so tap water still tastes like tap water even though the description says it adds minerals to make water taste good. I will only be using it if my life depended on it. Well intended product, but not for everyday use.

This is a good bottle. Bought it because the opening on the Brita one i had was a disaster to get ice in. This one has a larger opening and is much easier to refil!
