Keeps your coffee or tea hot and does not leak if it tips over. A winner for me!

Stainless steel double wall travel mug. If you put boiling water in it (then dump it out) before pouring in your drink, it will remain hot for longer. And if you chill it before putting in a cold drink, it will remain colder for longer. The top fits well, and there was no leaking when I turned it upside down for a few minutes.

This is a really nice stainless steel coffee mug. I also really appreciate the packaging it came in. Often items are coming in poor packaging or just in a plastic bag. The Mio Marino comes in a wonderful cylinder case, also read through their pamphlet and enjoy their website offering travel destinations. Pretty cool to check out. Now onto the product itself, stainless steel coffee mug. What you see is what you get in the picture, works well, and tested it with a warm cup of coffee in the morning. Kept it warm north of 5 hours which is solid because that's just in time for a refill. My only suggestion or change is that I'd really, really like them to make an additional LID that comes with the bottle or can be ordered separately. Just to have a bigger opening on the lid. This is a sipping lid and I mean really a sipping lid. If you want more coffee fast you won't be getting it that way. So can't really dock the rating for that -- just hope Mio Marino does actually produce a bigger lid for those of us that like bigger gulps. Caffeine on everyone! Edit: 8/15/20 - Added photos

This is a really nice mug overall. The bottom has a little grip to prevent it from sliding around, the lid and mouth piece seal tightly, it seems to retain a fair amount of heat, and fits in my car’s cup holder. Decently insulated too, so it’s not too hot when you hold it.

I use this travel coffee mug to take my coffee to work in the morning. I love the color and that it is lightweight. It keeps your drink warm for hours and fits conveniently into car cup holders. This is my favorite coffee mug.!!!

We are looking to have an alternative to a ceramic mug when we are on the go. And, this one is very nice. It fits well into the cup holder. And, it doesn’t hurt that it is plain but nice looking. So, I think it’s a nice alternative to a ceramic mug - which is fragile and does not hold heat.

I drink my coffee is pretty fast so I can't tell you how long it keeps it hot. I can tell you it fits in both cup holders in two different vehicles. you can turn it on its side, upside down as long as it's closed thoroughly, it does not leak.

Does anyone realize how many tumblers we teachers have? Lol.. I feel like a tumbler expert. 5 stars on this one. I prefer them a tad bigger but this is perfect for my 12 Oz coffee plus cream mornings (what I call a one cup day). The lid stays nice and snug - no drips. Cleaning is a cinch even though I hate none of these are dishwasher safe - but none of the good ones are. Just get a nice brush and it’s all good. Nice blue color and love the feel.

For me, this is a perfect travel mug. It holds 16oz., which is plenty for most activities. Because it isn't huge, I can hold it comfortably in my hand, even when driving. The lid fits securely, and the opening allows me to drink straight from the glass, or use a straw. It is a great insulator for hot or cold drinks. It is easy to clean. I like the brick red color, too. If you are thinking of giving this as a gift, it comes in a classy gift box that will impress the recipient.

The packaging was very pretty. It kept the mug protected. I love the color, it is listed as pink but it is more like a creamy rose. The size is perfect. One of the first things I did was fill it with water to check for leaks and there were none! That is something very important to me. Nothing worse than having your mug leak on you when you are trying to leave for work! Its pretty, it keeps your liquids hot for hours and doesn't leak. What more could you ask for? I love this mug! There is even a rubber cushion on the bottom to protect your desk or tabletop. Perfect! UPDATE when yoy add cold liquid cream your coffee doesn't stay as hot as long. Really hot maybe 4 hours. On the plus side there is this really cool lip indentation so you don't dribble while you drive😁
