ZOJIRUSHIStainless Mug, 16-Ounce, Lavender

Bought this for my mum when she goes out for a walk. Used it myself too. It does exactly what it says and keeps hot drinks very hot indeed for several hours. Top quality product and highly recommended if you want hot drinks while out and about. You may want to bring a mug to pour your drink into first as it does stay very hot. Haven't tried cold drinks but I'm guessing it will keep them very cold.

Very good quality. Easy to use. Comfortable to drink from. Keeps my hot drink hot until morning at least. Expensive but worth every penny.

Great product, really good insulation. Kept my coffee hot overnight and ready for the morning. If you fill it in the morning though, decant before drinking as it will be too hot.Not the easiest to clean however and if you leave the top to soak, it will leak water so make sure it's completely dry before you use it again.

Good

In fact. i cannot get this cup!Now what I don't know what is the situation, to the receiving station several times all have no

I really think this is the best water bottle to buy. Great size, not too heavy and keeps liquid at whatever temperature you put in it. Has a one hand clip lid that can be locked and a piece that prevents the flow being too fast and pouring down the front of you.

The thermos is a perfect size. I take it to the office every day with my coffee, and it keeps it warm really well. The color is appealing, although it would be even better if the price were a bit lower. Of course, it's a well-known brand, and it's worth the money.

Best thermos I have had. Early morning I make a test and bring to work. Four hours into my day the tea is still hot. Sometimes to the point I need to take the cover off to cool. Hot days, best for cold beverages with ice. Again, at the end of day there is still ice.

I filled this little guy up with hot coffee around 6:30 in the morning to go hiking. It was about 38 degrees out for most of the morning before I opened it up with my lunch at noon. My coffee was still HOT, not just warm but hot. I drank a out half of it, resealed the bottle, and went on some more hiking (all at an elevation of about 6000 feet) and had it again later that afternoon around 3pm. My coffee was still warm and enjoyable on a chilly day. 11/10, would buy again!

I work in a group home with adults with intellectual disabilities. They are delightful people, but one has a passion for stealing beverages. After losing my Coke (again), I decided to see if a locking commuter cup exists and this looked like it might just work. In order to take a drink, you must slide the lock over and then press the lever. Let’s just hope she doesn’t discover that the top unscrews.I've owned many commuter cups that promised to be leak proof. This is the first one that delivers. I can make my tea at home and carry it to work and not spill a drop.When I first received the cup, I thought I must have been sent the wrong size. There was no way this held 16 ounces. However, I measured it, and it does, indeed, hold 16 ounces. This is perfect for the 2 cups of tea that I make in the morning and for my 12 ounce cans of Coke that I drink when the tea is gone. (No coffee. Ever. But at least I don’t get that nasty coffee smell in the gasket.)Cold drinks stay cold for hours. This is great, because it can take me 4 to 6 hours to finish off my morning tea.I was a bit reluctant to try soda in this, because I have memories of my mom putting Coke in my Thermos back in the early 1970s and finding that the rubber stopper had exploded into tiny bits of sawdust or cork or whatever was inside the stopper when I opened it at lunchtime. I searched the comments here and found that others have successfully put soda in their cups with no mention of anything bad happening, so I was encouraged to try it. I am happy to report that I had no issues with a can of Coke in this cup. If I leave the cup sealed long enough between sips, I’ll get a soft “fft!” just like I do when I open a bottle of Coke after it has been sitting a while between sips. Thus, not only is my Coke kept cold longer in this cup, it retains the fizz longer. That makes this better than a Coke bottle.For the sake of a thorough review, I decided to make some hot tea near the end of a work shift. I put a tea bag and the boiling water into the cup and left the lid off for the 5 minutes it took to steep the tea. Then I put the lid on and waited another 30 minutes before I dared to test the tea. It was still hot, a little too hot to drink. I like my hot beverages hot, but this was too much. 45 minutes later. Still too hot. 1 hour. Too hot. 2 hours. Getting there, but it's bedtime. Too late to drink tea, unless I want to keep getting up all night. I awaken and in a bit I remember my tea. I test it, a full 11 hours after I have made it. It’s still warm. A little cooler than perfection, but drinkable.If there’s a downside to this cup, it’s that my small tea strainer is too large for the mouth of the cup. I have to strain my loose leaf tea into something else and then pour it into the cup. Otherwise, I get tea all over the table. I searched on Amazon for a strainer that’s small enough, and I don’t think one exists.Tl;dr: Leakproof. Keeps beverages hot or cold for hours. It delivers what it promises.
