This mug really is splendiferous. I tried another mug from Target the 'Senja Desktop Mug' (http://www.target.com/Senja-Desktop-Mug -Stainless-Steel/dp/B00149QDQ6/ref=sc_qi _detailbutton) and its performance pales in comparison to the Contigo Extreme. The Senja kept it warm for a bit, but not like the Contigo.In most normal coffee mugs, that are not vacuum sealed double walled, you have nice hand warmers in addition to a coffee mug. However, this mug fails at warming your hands. In fact, there is no heat transmitted to the outside on the walls, atleast as far as your hand sensors can tell. The only thats lost is through the sip hole, but even that can be closed to keep your drink hot for a long time. The ONLY downfall that I have noticed after about a month and a half is that the flip top, what you use to open or close the sip hole, seems kind of flimsy. I dont use it much, but it seems that it is already starting to wear a bit. However, even if this part broke off, the cup would be completely usable still. The lid seems to be holding well. One piece of advice: Dont try to HULK the lid on tight. Just seal it to the point of tightness and I am guessing that you wont destroy any seals, like other people seem to have noticed. Maybe Im just not as strong as them...oh well.Enjoy your Contigo, this is the best mug Ive ever owned
