360-degree Coffee--and a Hot Tumbler, Too
I have been using this tumbler since the days when it was listed as a Thermos product. It has changed little in that time, though it now doesn't have the mid-body rubber grip surface that it once had for a softer and more secure hold. (Its a loss to take it away, too.)
I can also compare it to the more popular Nissan "Ultimate" tumbler, since I bought one when I thought I'd lost this gem. Of the two, I much prefer the JMT401 for its handle-free design, and for the 360-degree sip capability. The handle of the Ultimate is a less comfortable grip, and it requires you to crank the wrist and to grip a smaller handle. You can't get away from the handle on the Ultimate, either, because you can only sip from the prescribed site.

buyers misunderstanding the description
I've happily owned this mug for many months after a friend recommended it. I never had a problem with it but I believe the low rating and reviews come from some misunderstandings about the product and the Thermos name.
Perhaps when people see the name, "Thermos", they are reminded of the quality flasks they make. Even though this is a travel mug, the Thermos name can lead to confusion with people thinking it works like a sealed flask. It isn't. It's a mug. It was not designed to be 100% sealed so throwing a filled mug into your backpack is a bad idea, and that applies to ANY mug.
Secondly, no where does it say it is leak proof. It is spill resistant, meaning if you drop it, it will not splash all over the place. ... Read More
Not a good design for car use.
The tumbler that I have is sold in various places as the '360-degree Dribble-Proof Tumbler', I am not sure if that is the same as the JMT401 but on paper the specs and features are the same. It is not a good design for car use. On the plus side I like the no-handle design and it has a small base which should fit most cupholders. On the down side you need 2 hands to twist the lid open or closed. Also the 'dribble-proof' design means that the mug has a very deep lip, and even when it is full you have to tip it far up and into your field of view to get the liquid flowing.
Good as a car coffee tumbler!
Good for automobile tumbler.
Toss a filled one in your travel bag the thing leaks.
apart from that the shape is good and the insulation is good.
Hence 3 stars.
If you intend to keep it in the car or prefer to hold it all the time in hands then 4.5 stars.
In other words keep it upright all the times.
Shake, it will spill.
