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

For starters, Miir tumblers keep things hotter, for longer, than anything I have ever tried and it's not really even close. Secondly, although some people complain about the top, I find it to be the best I've ever had. I use it for hot coffee and your really don't "drink" hot coffee, but rather you "sip" it. This is perfect for sipping. Also, some people have complained about not being able to tell if the top is open or closed, however, I have found that it makes a slightly different sound when opening than closing, so I haven't had a problem in that regard by simply listening. Lastly, some people have complained about the longevity of the top. I can't speak to that yet, so we shall see. I am hoping it lasts, because that last factor will allow this tumbler to be, in my opinion, the best on the market if you love hot coffee!

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.

Lid stopper has weak point at the stem. This broke on me twice, first time while washing in the sink, less than 12" drop and the stopper broke off. Too bad, I really like the size of this slim tumbler vs other brands, but will likely switch because of this. I can't keep buying new lids.

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.

I've owned two of the 12oz Traveler 360 thermos' and they are great for hitting the road with a cup of coffee. The seal is flawless, the size is perfect for a cup of coffee and the 360 lid means you don't have to take your eyes off the road to be sure the lid opening is in the right position. I had three drawbacks with the first one: hard to tell if the lid was opened or closed; the lid can't be disassembled for cleaning; and there's a fairly loud click when pushing the lid closed. The first issue was resolved with a marker in the newest version. For the second, I rinse in hot water daily and run the lid through the dishwaher once a week and it seems to stay clean. I've learned to live with the third. All in all, it's the best option available (and I've tried plenty!).

I love the shape of this travel mug. I can shove it into my back pocket if I need to, and it's easy to hold, even if I'm also juggling a bunch of other stuff (that's how my mugs get all dented and scratched -- from dropping them while trying to carry other things.) It also does a very good job of keeping my coffee hot. I like to sip my 2nd cup of coffee over the course of a couple of hours, and this cup is efficient enough to do the job.

This tumbler works great for keeping beverages hot or cold. It's not the very best I've had, but it's plenty for my use cases (keeping coffee hot for a couple hours so I can drink it slowly). Aesthetically, I really like it, which is honestly a big piece of why I chose this one over other options. I like that it's slimmer and straight up and down, rather than the style that's wider at the top than the bottom. However, the lid is really not great. The idea of being able to sip from any side is a good one, but the execution is poor. The opening is so wide that it's very easy to pour hot liquid down your front. Think about when you sip coffee – for me, I'm usually not having a wide open mouth, as wide as a smile; I'm actually sipping. That means my mouth is in a shape that's roughly 1/3 of the width of the arc that the lid is letting liquid out of... So you either end up with liquid pouring outside the bounds of the corner of your mouth, or you have to open your mouth WIDE open to fit around the very-wide path the liquid is coming out of – not a natural way to drink coffee. I don't know about you, but my natural instincts when drinking a hot beverage are not to open my mouth as wide as humanly possible and pouring hot liquid into it freely (see: the definition of sipping). Now, you might say, "But wait, it's the same arc shape as a mug – why is this any different?". Two reasons: 1) I'm not trying to drink from a mug while driving; that's one of the main selling points listed for this tumbler – that since you can drink 360, anywhere on the lid, you can drink while driving without having to look and see where the opening is; this negates that main use case, and 2) a mug doesn't have a giant stopped in the middle; it's much easier to tell when the liquid is coming and control it so only a little bit comes down, whereas with this design, it suddenly goes from "nothing" to "lots of liquid coming out in the full width of the arc", since it's otherwise blocked from flowing until you tilt it enough. I still like the visual design and thermal retention. I'll just limit this to situations where I can unscrew the lid entirely and sip myself. But that's a bummer, since the main reason to buy this tumbler for me was to have a way to drink coffee on the go.

Keeps hot beverages hot and cold beverages cold. This has quickly become my favorite tumbler for my morning coffee.

Love it

El termo funciona bien y está lindo. Sin embargo, el tema del envío muy mal, sí llegó a tiempo pero mi paquete llegó abierto. Creo que no está siendo muy buena idea comprar así...

Great product, super convenient I would have liked the lid to be made from metal also, the plastic used seems a bit cheap and especially if using hot liquids, I'd prefer a non-plastic option

飲み口の部分が分解清掃不可のため衛生面で不安がある。 説明書に煮沸・漂白はするなと書いてある。 開閉部が狭く普通のスポンジなどでは内部の洗浄は困難。 いや、無理である。 コーヒーやジュース類などで常用することは無理か？ 水専用のボトルと考えたほうがよさそうだ。 残念である。

Great product but hard to clean
