Purchased this S'well Traveler hoping its reputation was deserved. It is! This product, with the commuter lid, keeps my tea hot for hours. I can even leave it in my car when it is 35 degrees outside and come back in 2 hours with my tea still hot. Added benefit for anyone with arthritis or issues gripping with your hands, the lid screws on making it easy to put on and take off. Also, the tab on the commuter lid is comfortable to open and close.
