KEEPER TUM Insulated Iced Coffee Cup Holder

I love that the ice is slow to melt. It's just a bit heavy to carry around, and I'd love a version with a handle.

After about four or five hours the ice is almost exactly as it was. If I don't touch it at all for seven or eight hours it does melt a little, but if I'm drinking from it as I go it barely melts. The best.

A great product wherever I take it. The movie theater, the creek, the car — so many uses. The color is pretty and it keeps drinks cold well.

The color combinations are all ones I love, so choosing was agony. One lives at the office and one at home. Without a handle it's a bit awkward to carry around. And the important one: it doesn't fit my car's cup holder. So I'm going to try the smaller size. Apart from those two things I love it. Rather than the phone-strap style accessory on the side, I'd love a handle — my hands are small and it's hard to carry. I know that's my own situation, just a small wish. Fingers crossed the new smaller one fits my cup holder — off to order it.

Being able to drink straight from the cup I ordered at the cafe is so convenient. A small cup fits exactly; with a large cup the top doesn't go all the way in and sticks up a bit. I like that I can use it for water and other drinks too, and the ice definitely lasts longer and I can drink cold without worrying about drips. The color is lovely and I think I made a good buy.

I gave it as a gift and the person who received it loved it. I'd recommend it as a gift for anyone who works in an office.

It would be great if a lid that fits this tumbler came out too (so you could take it in as-is and get your drink without a disposable cup).

I bought a Keeper Tum as a gift, and the feedback was that it fits well in the car and keeps drinks cold so well that iced drinks last a long time. Apparently even left in the car in this heat the ice doesn't melt, and they're so happy they want another. As the person who gave it, that made my day.

Every time I went to the gym I'd bring a regular tumbler, pour coffee in, wash it after, and the next day there'd be a faintly musty smell. I got tired of it and found this — a revolution for me. Every time I buy coffee the owner or the staff look at it with curiosity. Tip: take the paper cup sleeve off before you put the cup in. The only thing I found inconvenient is the lack of a handle. If a version with a handle came out I'd buy another.

I like big tumblers so I bought this one. Washing a tumbler was always such a chore, and now I just drop in the takeout cup — so easy. It's cute and there's a spot to hang a keyring, which I love. It keeps drinks cold really well, so the ice holds up even when I'm out for a while.

I don't care about anything else, it's just so good. It's been so hot lately that an iced coffee melts before the morning is over, but the coffee that arrived at 8:30 this morning still has ice in it and it's almost 6pm. Please just get one. If you find tumblers a pain to wash it's a revolution, and as a trainer I drink a lot of water and reach for caffeine a lot too, so being able to finish anything while it's still cold is wonderful. For someone who wilts in the heat, this is a lifesaver. Thank you for making it.

This is the item I use most right now. I can put a cafe drink straight in without pouring it into anything, which is genuinely convenient. At home it sits on my desk, at the office it's with me while I work, and in the car it goes in the cup holder — I use it every day. It keeps drinks cold well and there's almost no condensation, so it stays clean to handle. Most of all the color combination is lovely, and with a cute keyring on it I'm happy every time I pick it up. It's practical and good looking, so I expect I'll keep using it for a long time.

Being able to drop a takeout cup straight in on my way to work is genuinely convenient. The best part is that my hand stays dry. It's not so dramatic that ice is still frozen solid overnight, but the ice in an iced americano I bought in the morning still has plenty of shape by the time I leave work, so I can finish it cold instead of watery. For everyday use that's more than enough for me. I like that it's large, and the colors — what can I say. I want to stock up on every one.

We bought two as a couple, and as an experiment I compared a plain coffee against one sitting in the Keeper Tum — the one in the Keeper Tum definitely kept its ice longer and stayed cold longer. I think we'll get a lot of use out of these driving around this summer.

At work I'd buy coffee and pour it into a tumbler to keep it cold longer, but even after washing there'd be coffee traces left and it bothered me. Now I just drop the cup I bought straight in and it stays cold. Love it.

I tend to drink slowly, so I often ended up with a watery drink by the end. Since using the Keeper Tum I can still have a cold drink when I'm leaving work, and I'm so happy with it.

And the colors are genuinely lovely. They looked good on screen, but they're much better in person. I bought a set in the pre-order and keep one at the office and one at home. I've swapped the silicone colors around to customize them, and there's a real joy in putting together your own combination.

I gave some to friends as gifts and the reaction was the best I've had. Function and design both — I trust this brand.

I brought coffee in a disposable cup and the ice didn't melt. I finished the drink, and with just the ice left I put it back in and left it — when I took it out later the ice was still there, and it melted quickly once it was sitting outside. I hope it holds up as well when I use it outdoors.

The ice doesn't stay completely frozen, but if you're someone who can't be bothered washing a tumbler, this looks like a good option. Carrying it around is hard though — I wish it had a handle. It would also be nice if they sold a lid with it.

It's so pretty — why did I only buy one? The colors are incredible. I washed it and used it right away, and it keeps drinks cold really well. I try to avoid plastic where I can, but in summer when I'm walking the dogs I order ahead on the app and grab the drink fast, so using a tumbler is awkward and I'd just take the disposable cup and watch the ice melt. This is made for people like me. A friend is coming over this weekend and I'm going to put a beer can in it.

Works very well

The delivery service is absolutely terrible. They just dumped the package outside the building... Even though the tracking number appeared and I tried to provide the building access code, they claimed the service wasn't available. It is truly the worst!!!!!!

I bought it to keep at the office and I love it. The ice doesn't melt before I leave for the day, and once I left it sitting in the tumbler overnight — the next morning the ice had melted, but the coffee was still cold. Money well spent.

It's big. I used it for a day and the ice lasts a long time — I had a cold drink for hours. The colors are pretty, and it would work well as a gift.

This has been with me all summer. Coffee I put in at night still has ice in it the next morning. I used to always end up with a watery, flavorless coffee, and since this tumbler I get to drink it fresh. The color is lovely too — I bought a second one for a friend.

I finished the iced coffee I'd ordered in the afternoon and refilled it with water. I didn't finish that, figured I'd deal with it tomorrow, and went home. The next morning I came in to clean it out and there was still ice in it — quite a lot of it. I already thought I'd made a good purchase, and this confirmed it.

It's great, but if I had one wish it would be for a lid sold separately. Sometimes I pour water and then get caught up in work and don't drink it for a while, and dust or bits can get in. Is a lid in the works? Please make one.
