Amazing cup!
Absolutely love mine. I bought one for my hubby cause the black color would come sooner then the rose one I wanted, of course I stole his for the week I was waiting. Doesn't leak keeps the temp pretty good. I drink my drinks fast though so I'm not sure how long it keeps the temp for. I like that it's easy to clean and a beautiful color to boot.

Great cup! Seal works! Will repurchase!
THE best cup. I love mine. I see other comments talking about the seal not keeping things separate. Then youre not putting it on right. Ive had my cup over a year now. Ready to invest in another. Keeps my drinks hot most of my 8hr shift. Cools down into about 6 or 7 hours. My cold side stays cold longer. The only thing I can say is its hard to get my hand in to clean it. So, the dishwasher does that part for me! Overall, great cup!!! Will definitely be buying a few more as gifts and 1 more for me!

Doesn’t Stay too Hot or Too Cold but I like it
I’ve edited this review a couple times because I have a love hate relationship with this cup. The color is as pictured. A pretty (similar to forest) green. Logo on the side is not obnoxious. It is large but it’s easy to hold. It BARELY fits into my cup holder (doesn’t fit all the way into it, kinda sits on top of it but doesn’t fall over). I like the shape of the built in straw (rectangular) feels nice/natural but it doesn’t bring up much liquid like a big straw does and I feel like it’s too short. The straw has a “rubber” neck that has to bend/flex every time you open and close it so I’m hoping it won’t fail there quickly! Only time will tell! The lid fits nice and tight as advertised and does close with a quarter turn which is nice but it’s a little hard to find the right spot when trying to line up the straw correctly but I’m sure it will get easier as I get use to the cup!? As you can see I want a straw on both sides so I just slid a straw into the opening and it fits fine! I ended up finding taller straws that fit great and stick up way higher.. (yay) I added hot coffee to the hot side and ice water to the cold side. Sipping on my coffee is comfortable through the lid. I closed the lid and cooked breakfast and came back to it 45 mins later and it’s barely lukewarm. :( I tried my husbands coffee in his thermal mug that we LOVE that we poured at the same time and his is still sooooo HOT it almost burnt my lip. So, I think I will stick to cold on both sides for me which is why I bought it. You choose for yourself but my hot/cold experience wasn’t a 5 star! Sitting side by side with my yeti for ice ..the yeti lasts why longer too .. So, overall don’t buy this because it’s going to stay hot for a long time or stay cold for a long time because it won’t. Buy this if you are like me and you want a nice cup that will hold 2 different drinks without you having to hold 2 cups! Have realistic expectations and you won’t be disappointed with spending $50 bucks on it!

Good Idea but didn’t deliver unfortunately
I really wanted to love this product. I gave it a shot and tried multiple ways to use it. to start the seal that’s supposed to divide the chambers is not great. I have coffee on one side and water on the other and when I finish my coffee and I open the lid to check you can see the water has a foggy appearance so you can tell coffee has mixed with it. I know it is not my placement of the lid. I know it is properly places and locked in place. I think the heat or steam pressure from the hot side affects the seal. The describe time frames for each liquid listed for cold and hot is completely inaccurate. I’ve put hot coffee in there fresh from the pot and had it stay for about 40 minutes and you get a warmish room temperature coffee nowhere near hot. I’ve even tried to preheat the hot side by filling it with boiling water while I brew my coffee to hope to extend the time that it keeps it hot, but it’s the same thing, about 40 minutes. You have warm coffee, not hot water. Onto the cold side, the water does not stay cold. It is slightly cool. I filled the side up with ice more than water thinking I can keep the ice and continue to add water if need be and when I do add water it’s cold water out of a filtration system, but the ice does not stay in the container for long. It melts pretty quickly even when using cold water to add to the ice and I’m not sure if that’s because of the heat from the coffee side doing something to the ice and causing it to melt faster, but by the time I’m done with my lukewarm coffee and 40 minutes, my water is barely cool. There’s no ice in there and it has the hint of coffee that has mixed into it. I love the size of the cup. The amount of liquid that each side can hold is perfect as I would be refilling both throughout the day anyway . It’s comfortable to hold in your hand, even with the cup, not having a handle if it’s great in my bag standing straight up in its sleeves, so it’s not tipping over the bottom is no slip so everything works perfectly. The ease of cleaning it with a brush is perfect. The color is beautiful, but the functionality does not live up to the description. I hope they make a version two and another go at this because I would really love to have one of these that can truly keep the liquids separate. Maybe they need to rethink the insulation and create more of a barrier between the cold and the hot sides so that they stay hot and cold.

Probably the silliest thing I’ve ever bought but it works as intended

This product says that it holds boiling water for around 8hr and cold for around 12hr, this is not the case at all. It holds boiling water and after around an hour it is warm, and will stay warm for about 3hrs, but not hot. Same as cold the ice was gone within an hour and room temperature after 5hours. The idea and practicality however is good, having 2 drinks available in the one cup is great. I also wouldn’t make myself a coffee and drink it 8hrs later so that doesn’t bother me as much. Mine does leak (not massively) but it definitely does, it is not spill proof (may be a fault in the my lid) but I am just careful. In total it cost me $108 AUD with shipping and honestly I don’t think it’s worth that much but like I said the idea of it is great and it does last at least an hour or 2 so I’m happy with that

Tolle Flasche mit super innovativem Ansatz. Löst einige Getränke-Logistik Probleme und es funktioniert auch für Getränke mit Sprudel. Einen Verbesserungsvorschlag hätte ich noch. Der Kipp-Winkel für Heißgetränke beim Autofahren ist zu steil. Ich stoße an die Decke. Es wäre super wenn es eine Deckelvariante mit 2 Strohhalmen gäbe. So muss ich separat noch 5 Euro für ein Silkonstrohhalm drauf legen. Insgesamt trotzdem super <3
