The water bottle itself does a good job of keeping water at a constant temperature. However, the bottle comes with a caribiner and attached ring, so that you can hang your water bottle from a backpack, belt loop, etc. The metal ring that attaches the caribiner to the lid has already started to twist out of shape, less than a week after the bottle arrived. Again, the bottle itself is great - but the ring clearly wasn't stress-tested as it ought to be able to hold the weight of a full bottle or it shouldn't have been included as a feature.
