Thermos Nissan 18-Ounce Stainless-Steel Insulated Travel Tumbler

Overall this is a pretty good travel tumbler. With its vacuum layer between the outer and inner stainless walls it provides hours of piping hot beverages on the go.

A few caveats however. I was absolutely stumped why the manufacturer would not create a venting hole in the lid to allow for air exchange as you're drinking. As a result of this oversight the hot coffee will often hold back as you tilt it to drink, only to come gushing onto your upper lip in with red hot fury when the liquid tension is broken. A 1/8 inch hole drilled quickly into the lid solved that problem with little fuss.

Second caveat: after using the tumbler almost daily for a year or more you'll begin to notice discoloration of the inside. Doesn't seem to affect the flavor of the drinks but it's strange nonetheless.

Third caveat: if you put it in the dishwasher repeatedly the black rubber sleeve will eventually get gummy and sticky. I learned my lesson with the first tumbler of this type that I owned and only hand wash this one.

Fourth and final caveat: The flip-top tab that's supposed to minimize spillage is annoying in that, once you flip it up to sip your beverage, you are rewarded with a dot of coffee on the tip of your nose. A drop of coffee always gets retained in the flip-top tab and you have to remember to blot it out with a napkin to avoid this. I'm sometimes slow on the uptake so it took a while for me to remember this in time to avoid it. Certainly not the end of the world but a little irritating.

Despite all these quirks it's one of the better ones I've come across and is worth the price in the end. Especially if you own a drill.

This is the third Nissan insulated travel mug I've owned. It's the only one that keeps liquids hot most of the day.

I am SO happy to have this mug. I had the same mug for over 15 years and just recently left it somewhere. I was heartbroken and so excited to find the same product still on the market. This mug will keep my coffee warm for hours and what is really amazing to me is that it will keep my drink cold when left in my car in the hot California sun for over an hour. My thumbs up
to Nissan for the design!

It is comparatively toll, but surprisingly it never slips from car cup holders.
It really keeps coffee hot for four hours and is very secure to hold in your hand.
I bought two of this for my self and my husband and we don't use any of our old cups anymore.

The other reviews are right! This is a great travel mug... coffee/tea stays hot for a long time (4 hours), especially if you heat the mug beforehand. Would recommend spending that "little more" for this product!
