THERMOS Stainless King Vacuum-Insulated Travel Mug - 16oz Leak-Proof Coffee Thermos, Double-Wall Insulation Keeps Drinks Hot/Cold for Hours - Perfect for Commuting, Camping & Office Use (Midnight Blue)

I received and used this Thermos cup today. First impressions are that it is definitely 5-star quality. I chose it for the the graceful design and the size. I’ve had Yeti, but they are often too bulky for my taste. I also liked the color selections and chose the midnight blue. It’s a really nice rich color. The finish has a deep hue and a high quality feel.At 14 oz, this is a perfect size for commuting or traveling. I had some concern about how long this one would keep coffee hot because I’m a sipper and a cup can last me for three hours or more. I rarely finish a cup that is actually warm unless it is left on a warmer.I prefer a handle when and the open end of the handle makes it eqsy to hang the cup on something if my hands are full The cap is designed really well, and when closed the cup can’t leak even when the coffee is hot. It appears that hot coffee will exert extra pressure on the inside causing the inner seal ro press more tightly. That’s a nice feature. The cap opens with a lever that makes it easy to open or close the lid withjout using two hands. Also you can drink coffee from either side of the mug, i.e., left or right handed. Actually, I was wondering if the lever would bump against my nose, but it is designed to be off to the side when open. With the lid is in the open, it let’s a reasonable amount of coffee through, but with any care at all, you won’t be likely to burn yourself because it's easy to regulate the amount coming into the “sipping tray” part of the lid.So the first test: I made coffee at 1 PM and an hour later, the coffee was still remarkably hot. Rather than test the long-term holding power, I decided to leave the lid open to see how quickly tmy coffee would cool. What a surprise: I finished the coffee at 6 pm and it was still a very pleasant drinking temperature. Five hours is better than my Ember cup by far! Finally, when I came home s disassembled the lid to wash it and it was very easy and intuitive.Honestly, for the money, I’d say it is the best hot cup I've purchased, and I’ve gone through quite a few. Definitely would recommend it.
