Temperature Control Travel Mug 2, 12oz

This is stated on the Amazon page but I missed the significance of it. The top temperature is 140 degrees. For perspective, Keurig dispenses coffee around 165 or more and searching revealed that many "coffee experts" recommend hotter than that. 140 just isn't hot enough to be enjoyable. The controls are a case study in form over function. They are beautifully embedded into the cup. Personally, I can't imagine a better aesthetic. Working them, however, is a nightmare. Just getting them to show up is a challenge much less operate them. These two fatal flaws compound. The controls are a bit better and somewhat manageable after about 20 minutes when your coffee has cooled to lukewarm. In the meantime, they are virtually impossible. So, here's how it goes: 1) Insert wonderfully piping hot coffee 2) Have absolutely no control over anything and just have to wait 3) At some point, take a sip and notice that your coffee is outright cold. 4) Now you can, with luck, get the controls to come on and tell it to reheat your coffee up to 140 degrees. If you have access to a microwave during your coffee enjoyment, it is FAR easier and better tasting to use a regular mug and just nuke your coffee for 30 seconds if it gets cold. I strongly recommend against wasting your money and this flawed device. Manufacturer: I LOVE the idea of this mug. Please crank it up to 160 or more max degrees and put some actual controls on it. It's OK if they aren't perfectly beautiful. The first priority is that they work. (In other words, step up, stop letting attorneys and product designers run your company. Re-take control and prioritize customer experience and operations.) If you make those changes, I'd buy it and would, I admit, pay even more for it.
