MiiR 360 Traveler, Stainless Steel Double-Wall Vacuum Insulated Tumbler - Leakproof 360 Lid for Easy Sipping on the Go; Perfect for Hot & Cold Drinks

This a nice large coffee/tea travel mug. It keeps your drink hot or cold easily.

Nice and compact for hot liquids. I do not like to carry large coffee cups so this was ideal size. it fits in the side pockets of my bag during travel. One issue in the beginning was to know how to tell if the lid was locked or not. I must have pressed the top few time not realizing that the top was open, end up spilling coffee on my shirt. other than that, I love using it for its compact size and dfsleek design.

Keeps water cold even on 80F hot days trapped in a car, 8 hours later. Amazing. It is hard to tell if it's open or not and figuring out the correct pop sound isn't intuitive or easy. It does seal and not leak once closed up. Lightweight. Can drink from any side. Worth the value for me even if it means popping the top a few times to make sure it's open or closed; Far better than it spilling in my backpack.

Revised - I figured out the flow/no flow thing by reading another person's review (thanks for that), so I went back to loving it. Today, when getting my stuff in the car to go to work (briefcase, purse, lunch, coffee thing, etc) I put it on the roof of the car, got my stuff in order and drove away. Guess what happened next.Yeah, that. At the first stop sign it slid off the roof of the car and I watched it tumble in front of the windshield, bang on the street surface and roll down the street. It's not even light out yet, and I'm running down the street after it. The little disk at the top broke off and since it was dark I was not able to find it. The reason I changed my review to 5 stars was that when I got to the office, I could do NOTHING until I got on Amazon and ordered a replacement. No consideration required. Now that's love. But just to be clear, the top broke because it hit the pavement, not because it's cheap. Totally my fault.Old review:I used this for basic office coffee commuting every day. I loved it! The size was perfect, the shape was pretty, It was perfect, until it wasn't. The way it closes is kind of unique, but it wore out after a little more than 2 months. I guess it's beyond the return window, so yeah...I actually liked it enough to buy it again knowing that it will only last 9 weeks, which is bonkers, but if you're a rational person you may want to keep looking.

Great pop-top lid that lets you sip at your own pace, without burning your lips if there's extra-hot coffee in it. Also very stylish design, simple, understated yet extremely functional!

Yes, shame on me for not doing more research, but not being able to tell if the mouth is open or closed is a huge design flaw and potential safety issue. My wife had made me coffee and she thought the mouth was closed and while I was walking to my vehicle the container tipped and to my surprise hot coffee flowed out and burned my hand. For that safety reason alone I would not recommend this product.

Very nice quality as far as material and construction, and does a great job of maintaining beverage temperature for plenty long enough. The only two issues for me are that it can be hard to discern whether the drinking lid is open or closed just from looking at it, so you have to either make sure to pay attention and remember or try to drink out of it in order to know and make sure it is closed, and then that the fact that the entire ring around the lid opens and you can drink from anywhere around it; it’s a double edged sword since it is both convenient but also increases the risk of possible leaking, particularly when full. Overall it’s a very nice, quality travel mug that does keep beverages hot and cold quite well, but next time I would likely opt to try a different model and/or brand with a different one-handed operation model due to the couple of (in my opinion) drawbacks.

I have a can cooler by this company, a gift from my son. That cooler does an amazing job of keeping soda and beer cans chilly and enjoyable. So I thought I’d give this travel mug a try. Wow! It keeps my coffee hot for at least three hours, and very drinkable for a long time after that. I no longer have to overcook my coffee in the carafe, nor keep zapping it in the microwave, and I can drink it at my leisure. Wonderful. And it’s spillproof and easy to use in the car. The hand washing is a trifle less convenient than dishwasher, but it’s well worth the quality this product delivers!
