LEIDFOR 16oz Stainless Steel Insulated Coffee Travel Mug - Double Wall Vacuum Thermal Tumbler, Leak-Proof & Sweat-Proof, Keeps Hot/Cold for Hours - Perfect for Commuting, Office & Outdoor Adventures (Black Dragon Design)

I am a big fan of the portable insulated coffee/tea/water cup. I let the gasket of my Bodum cup go down the disposal so had to get a new one and Bodum doesn't seem to make them anymore so I had to go shopping. I liked the way this one looked and it had good reviews so I tried it. It is a little work of art--absolutely beautiful and a delight to hold. I bought it because it is made with a stainless steel interior--all the ones I've had before said stainless but were not stainless on the inside and who knows what kind of metal was really in there? But this one says stainless and it looks like stainless to me.As for its performance, it does keep beverages scalding hot for quite a while--longer than my commute I'm afraid and so I would not be sipping out of this right away in the car. But, that is great once you get to work because it will still be hot. I use these cups for a different reason actually. I am not a fan of super hot or super lukewarm. I like it just off the hot scale but not where it has become like bathwater. Sort of like hot enough to still be HOT without burning your tongue. And hot enough to still taste good. But I also enjoy those few degrees right above WARM as it naturally cools down. So, I use these cups more like a thermos to pour out a little at a time into a cup. I drink that and pour a little bit more. This cup will keep the temperature just right for hours. I usually finish it off long before it cools off too much and go make some more--tea usually. I have put water in also at that just right spot below ice cold but well above bathwater. It lasts like this perfectly even in our still hot Texas weather while I'm driving around and is a joy to sip.So, I've praised the cup and do recommend them. But, because of the way I use it, I must add that it's not really made to be a pourable "thermos" type cup. It's designed for a very smooth sip--perfectly designed for that. It does leak a little when I pour it out into a cup. But I already love it so much that I put up with this minor inconvenience and just put it on a napkin or towel at my desk. If I do let tea sit a long time, it gets to a perfect sipping temperature and then I finish it off like that.I even enjoy washing it because it is just so well designed. I meant to write a review right away once I unpacked it and saw what a thing of beauty it really was. I kept trying to think of how I would describe it so you might get some idea. I procrastinated though and am embarrassed they had to ask for my feedback a number of days after my purchase. So, I hope my review does it justice and you might consider it as you wander aimlessly through the Amazon aisles :)I do think I might try their other cup which is for coffee and might be good for pouring! But I'll never give this one up. I may have to have more than one of these.
