About how long does it keep hot beverages hot? Longer than the plastic double walled tumblers?

Yes. It keeps a cup of coffee hot for about 20-30 min. The lid is the shortcoming. It's silicone so it smells plasticy and isn't that secure - not like a screwed on top. It works.

If I prime the cup before putting hot coffee in with a small amount of boiling water (as I'd do with any double walled container) it will keep hot coffee hot for the better part of a work day. Not piping hot, as it does lose a lot of heat through the lid, but it's hot until lunch and warm in the afternoon. However, I'd put ice and water in mine and let it sit over night and gotten up the next morning to still have ice in the tumbler. (This is all to say, yes much longer than plastic, especially if you prime it with boiling water first.)

Yes, longer than the plastic double wall tumblers. I drink coffee all day long and it keeps it hot for 3-4 hours minimum. Depending on the outside air temperature of course. I absolutely love these tumblers. I now have purchased a total of 3.

I am tempted to just answer "hours", but of course "it depends" (sorry!). I think if you just pour from a freshly brewed pot of coffee into this awesome Nissan-Thermos stainless-steel mug, you should easily get at least 2 or 3 hours of hot coffee. Personally I drink 14 oz. of coffee much faster than that! But the real trick to this double-walled, vacuum construction is to PRE-heat the cup! First, run hot water from your tap (as scalding as you want) and then pour it into the cup, close it, and set it aside while you make your coffee. I assume the vacuum (?) stainless-steel gets heated up. Then, when you dump out the hot water moments before you pour your hot coffee in, it's almost as if you have a heated thermos! Using this method before a 2 hour commute I don't even notice a decrease in temperature at all. It seems to me that it will then stay hot 4 or 5 hours or even more! Obviously I am a huge fan of this "Nissan" Thermos brand.

I believe that that this one keeps hot liquids hot for over 6 hours and I swear mine keeps hot for 8.

Debbie, Truthfully, I purchased this for a gift. The person I gave it to said it keeps her coffee very hot on the way to work, she lives 50 minutes from work. She also stated when she arrives the coffee/drink is still as hot as when she filled it. Hope this helps, Spencer

I only used it to hold hot chocolate and cider but it looks like it would be quite fast because it heats up almost immediately and I would guess about 10 minutes. Maybe a better question for someone else.

It is better at keeping cold drinks cold, but it will keep coffee hot for hours. Beware of opening though, it may squirt a few hot drops out of the straw due to pressure build up. The regular Thermos containers without straws are a better purchase for hot drinks.

It's a porcelain cup which, to my knowledge, can't be double wall insulated like a plastic cup. But it does have a nice insulated band of blue rubbery material that insulates your hand and partially insulates the contents of the cup keeping it warmer longer. Additionally the cup is small (8 oz) which I like since the contents stay warmer just due to less surface area in which to loose heat. Therefore I'd say it is insulated much better than a regular large porcelain cup even without being "Double-walled." Hope this helps :)

They are double walled and will hold hot beverages well - similar to any stainless double wall coffee cup. The outer wall will get warm tho', hold by the handle!

These keep drinks piping hot for hours. I'm not exaggerating when I say at least 8-10. You have to make sure you don't put it in super hot or it will not be drinkable for hours. It's that good.

I wouldn't use it for hot beverages myself, though it would certainly keep them hot. The problem is, it uses a straw, not a "sippy-cup" style spout, so it would be very easy to burn your mouth badly. Also, though the mouthpiece is silicone (and thus would be fine with even the hottest drinks), the straw is (BPA free) plastic, and I'm not sure how well it would hold up to heat.

Couple of hours. Of course coffee gets cooler over time - still warm after 3 hours but not hot. Mug is well insulated and works about the same as other double-walled aluminum insulated mugs.

Maybe about an hour. There is no closure to the lid so things do not stay as hot as i would like.

Around an hour. The plastic lining changes the flavor of coffee however, I would highly suggest a thermos with a double walled stainless steel lining.

It varies with the beverage and whether or not you used hot water to heat up the mug before you put your beverage into it. Good 4 hours sometimes longer. Imagine it would be shorter time if in a cold area. I keep my car warm.

The coffee stays hot only about 1/2 hour. It is double walled stainless with no insulation.
