Query: Lukewarm

This does not keep liquids hot even if I prime it with hot water for awhile before dumping that and adding hot tea. Seriously, liquid cools in less than 15 minutes. Sipping from it with the lid on is unsatisfactory, you barely get a mouthful. I find that you have to unscrew the cap and take it off completely, which defeats the purpose of a travel mug. I do like the handle though. It's a help when juggling packages and doesn't interfere with the cups ability to fit in a car cup holder. I just wish it kept things hotter.
