2-in-1 Hot & Cold Vacuum Insulated 30oz Tumblers, Stainless Steel Dual Chamber, Leak-Proof, BPA-Free, Fits Cup Holder, Travel Coffee Mug, Split Cup, 2 Drink, 2 Sides, Coffee & Water (Harper White)

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!

I use this tumbler every day. Iced coffee in one side, sparkling water in the other—and it works exactly how I hoped. Both drinks stay at the right temp for hours, and there’s no flavor crossover at all. One of my favorite things is that it’s actually dishwasher safe, which is pretty rare for reusable tumblers. It’s easy to use, doesn’t leak as long as the lid’s on right, and looks sleek too. If you’re someone who always has two drinks on hand, this thing is a game-changer. And yes, it does fit into my car cup holder!

Holds a good amount of drink and keeps appropriate temperature, leak proof, fits in carry on bag.

No leakage, no mixing. A lot easier to set up than I expected. Kept two drinks cold on a hot day. Color matches the photos. Would absolutely buy again, but I don’t expect to need to, as it seems very durable.

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.

I used to carry both my water Stanley cup and coffee Yeti to work every day, so I needed this cup before I even knew it existed. After using it for a week, here are my thoughts: I was initially concerned about the lid based on previous reviews, but it seems they’ve made improvements. My lid works perfectly—it’s easy to open and close. You just need to press down slightly and twist. It takes a little getting used to, but you’ll get the hang of it quickly. Each side holds 15 ounces, which is good if you’re like me and finish your drinks within an hour or two. My hot drinks stay piping hot to the end, and my cold drinks remain pleasantly cold. There might be a slight temperature change by the second hour, but it’s negligible. It would have been nice if it held more liquid If you are the very thirsty and always dehydrated type, but for most I think this is good enough. The center strip on the lid needs to match the center strip on the cup to ensure it’s 100% leakproof and to prevent mixing. Once I did that correctly, my Splitflask didn’t leak, spill, or mix. The design is top-notch. The intricate lid and dual chambers are remarkable. It’s comfortable to hold and fits perfectly in my car’s cupholder. Overall, I’m very happy with this cup and hope they make a 40oz size to replace my Stanley cup.

I was excited about the idea of ​​cold and hot and ordered it specially for Germany. It's a pretty big thing, with the corresponding weight. You don't just carry it around with you and it doesn't fit in every bag. The workmanship is good and it looks good too. But now comes the thing. Yes, you can fill it with cold and hot drinks. Yes, it is divided by a partition. But this partition is not very thick and the lid is made of plastic. This means that the hot drinks cool down more quickly than expected and cold drinks don't stay cold for long. The lid in particular is the weak point here. Do the drinks mix? Not in principle, although my cold drink did taste a bit like coffee at the beginning. Is the tumbler leak-proof? Yes, absolutely. On the whole, the workmanship makes a really high-quality impression. Sending the item back is uneconomical, so I'll keep it, but will probably only fill it with different types of cold drinks. I can't really recommend buying it, it's a bit of fun but actually rather impractical. One more note: when you open the side for the hot drink, the top of the cap has something like three small holes, see picture. The liquid always gets caught in these and when you drink it drips onto your face. So I always have a tissue with me and dab these openings after opening so that I don't get dripped all over myself.

This is SUCH a great idea. I did not enjoy carrying around 2 insulated cups for hot and cold. I was dropping them all the time. I put this Splitflask in a carrying sling, and now I don't even have to think about it. And this cup can handle some abuse too.

Very carefully and thoughtfully designed! Excellent quality and functionality. No leaks, no mixing and temperature retention as described. Wish I got this sooner.

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

Had it for over a year. I used it everyday at work. Sometimes i put water sometimes I put another drink next to my coffee or tea. Absolutely amazing once you get to know how to use it properly so it doesnt mix the drinks together. Only thing I wish it was cheaper so I can get more colors and wish it came with the car holder.
