Keeps coffee, hot and is spillproof
I can put my tea a coffee in it and shake it and nothing ever leaks and I can carry it sideways and it keeps everything hot and it’s easy to drink out of.

Revised: I love it again.
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.

Almost…
I love this style. It’s my favorite kind of cup. It keeps the coffee hot. I have another one of this brand and a taller size that I like a lot. However, this particular one after a few months of ownership I was having trouble closing properly. The push down doesn’t work so well anymore.

Hard to tell, if open or closed!
This is a great looking product, but the functionality is a little bit subpar. Love, the fact that you can drink from any side of it from the top, but you really canât tell whether itâs open or closed, which is a problem and annoying times. But for what itâs worth,it looks really nice and it seals pretty good.

Love
I travel on the train/uber to work and this is the perfect size to carry in hand and in my backpack. Hard to tell if I locked the lid without trying to take a sip first but no big deal. I also like that you twist the lid on vs the typical rubber seal so I know it won’t leak. Happy with my purchase!

Perfect size, very efficient
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.

The lid is not of quality compared to the physical bottle itself. It feels cheap with no structural integrity.
