OK,
Well, I finally bought the Nissan Thermos Leak proof stainless steal mug ( pant pant pant ).
It sucks, it doesn’t keep the heat for longer than 30 minutes. It's really terrible and the build quality is really low, it's really trash.
NOT
Ha-ha, got you. This mug is superb. I got it for (26 US) and had to pay extra for shipping (14 US). I had to wait for about 2 weeks to receive it. But it was worth the wait. At first I had my doubt about it. The bottom of the mug was at room temperatures regardless of what you put inside it. But the cap gets really hot and I thought that it wouldn’t hold heat for more than 2 hours at most, but boy was I wrong.
It can hold heat for 4 hours with the cap opened enough for you to drink. I measured the temperature of the tea after 4 hours. It was at 47.8 C°. I measured it after 6 hours and it was at 37.8 C°. Just to give you a frame of reference of how awesome these performance numbers are, my last two expensive but useless stainless steal insulating mugs would be at room temperature ( in my case 19 C°) at around 2. And they would have already lost their heat by the first hour.
Needless to say, it performs even better with cold drinks. I put ice inside the mug along with a soft drink and it kept the ice from melting for around 3 hours. I even put in cold drink without ice, and it held it for 2 hours ( I finished the drink before I could find out how long it would remain cold, no will power).
And of course, there is this whole leak proof issue to be amazed by. It really works wonders at justifying the price tag for those who would doubt your judgment in money spending. This thing really is absolutely leak proof! You can fill it up with soft drinks like Pepsi, shake it like Shakira, and it still wouldn't even make squeaky sound, the sound you would hear when air is escaping form the cap. Good luck opening it up afterwards thought.
You just have to love the way the cap works. If you tighten it up, it's as leak proof as a submarine. But if you want to drink from it, it excels even further. You screw it open and you choose how much liquid you would like to seep through the cap. IF you open it just a little bit, you can drink tea while lying down on your back. A very stupid thing to do, but it does show how clever the whole package is.
So, to cap it all off, Nissan Thermos, was not the miracle worker that I thought it would be ( I'm a physicist, my standards are unreal) but this mug does something I have never seen in other stainless steal insulating mugs, IT ACTUALLY WORKS!!
Thank you very much CARGUY and all the rest of you for your help. I really appreciate it
