Keeps beverages hot or warm for more than 12 hours
Recently, within the past couple of months, I have purchased two of these Thermoses from Amazon. I was attracted by the Thermos reputation for quality products, the pleasant appearance, stainless steel triple-walled construction, and the expectation of keeping hot coffee and teas drinkable at desirable temperatures for long periods. I have found that if I fill one of these with a hot beverage just barely cooled enough to drink comfortably and close both the inner stopper and the outer lid, the coffee or tea stays hot for long hours and is still warm enough to enjoy after as much as 13 or 14 hours. This includes drinking from the Thermos several times during that time. Mostly I use these excellent containers to keep by my bed overnight to drink a few swallows each time I wake up to go to the bathroom. I’m a man in my mid-80’s and usually get up at least twice or three times, sometimes four if I’ve drunk a lot of beverage before bedtime. Because coffee acts as a diuretic in my body, I try to refrain from drinking any caffeine after 2:00 PM, but occasionally I drink a little as late as 2:30 or 3:00. I do not agree with those reviewers that these Thermoses fail to keep the beverages hot or warm for 12 hours, as the seller/manufacturer claims. To reiterate, I believe the secret is to keep the stopper and lid tightly closed and not allowing the container to stand opened for any length of time. My one complaint, if any, is that the top opening is so small. I do not understand why the instructions for use state do not drink from the uncovered opening — I drink from all the of the containers I use directly from the uncovered opening, as I do not care to drink through openings in lids or covers. Because of the too-small opening, I have to mix my beverages in another container in order to add creamer for coffee or cool water for tea, and then pour the beverage into the Thermos; stir well, then pour into one of these Thermoses. This works best for me but should not be necessary if the uncovered opening were larger for normal drinking. My rating is 4-star instead of 5 because of the too-small opening.

Keeps drinks cold for hours, doesn’t leak. Trustworthy brand!
I use this thermos to keep my 12-month-old’s whole milk cold while we’re on the go, and it’s been such a helpful tool during our transition from ready-to-feed formula. My son still likes to have milk during car rides to and from daycare, so this has been a great temporary solution while he gets used to drinking from a straw.It keeps the milk cold for hours, fits easily in a diaper bag, and doesn’t leak. Super convenient for busy mornings and definitely makes the transition smoother for both of us!

Great item. Keeps drinks hot. No leaks.

Have been using this product for the past month and it’s been keeping my water warm overnight for at least 8 hours! Better than any of the other hot water thermos I’ve been using previously
