I love my S'well bottle and I bought this Traveler thinking it'd be as good as the first one. BUT the Traveler does NOT keep the temperature of the water (cold) even for 6 hours... it loses temperature quickly for a triple layered bottle. I've tested it with its regular lid and with the other one that came with it (which I've been using with since I bought it), both deliver the same result. However, even with this fact, I still think it's above average.
