S'wellStainless Steel Tumbler with Straw and Slide-Open Lid, 24oz, Marble Swirl, Triple Layered Vacuum Insulated Containers Keeps Drinks Cold for 18 Hours and Hot for 5, BPA Free

I got this to use in my home office. I do a lot of video calls with clients and when I’m drinking something it looks more professional drinking from a straw than it does tilting your head back to drink out of a bottle. My schedule also requires I sit for long periods of time without breaks so it was important to have a cup that keeps things cold for a long time.I wanted to test how well it did. I put ice cubes in room temperature lemonade. I drank the lemonade within about 30 minutes and continued to monitor the ice cubes throughout the day. At the end of the day, about 10 hours later, the ice cubes were still solid and only down to about 3/4 of its size. The cup doesn’t have any condensation on it either.Not only is the cup nice to look at, it also has a textured feel to it. This is great for making sure the cup doesn’t slide out of your hand.The straw is metal and small in diameter. I wasn’t sure I would like drinking out of a metal straw, but I didn’t mind. I highly recommend this cup.

This cup is an eye catcher! The colors are so vibrant and beautiful. Holds the ice cold liquid for a long time, I don’t know the exact number of hours but it was most of the day. Even once the liquid was gone the ice remained for awhile. I love the straw and the silicone covering it. It didn’t leak while I was using it, and i didn’t test it out in lots of scenarios that I’d never use it in. I used it normally for me and I like it. Got a couple of compliments on it too! I love the colors and have a hard time not looking at it.

I absolutely love this travel mug! It keeps beverages warm throughout the day and cold with ice overnight! The sizing is perfect, it fits in a car cup holder & fits well in my hand. It is easy to hand wash and the straw is bendy! I have no issues with spill and absolutely no sweating. The colors are just vibrant and gorgeous. The quality seems stellar. The lid has a good suction and is spill proof. The cup does have a soft texture of the design on it. Works great and is versatileEdit; this is the best cup! The ice stays good for 48 hours! It amazes me this is incredible insulation I love it and keeps drinks hot ALL day too

Everyone is obsessed with insulated cups these days. Well, so am I, but I am not a collector. I like to have one good cup to use at a time. Right now, this is my main squeeze. It is so good looking and built so well. The quality is really high. This is a trusted brand so I was not surprised. The marbling is really beautiful and vibrant. Because I am spending a lot more time outside right now I appreciate that this keeps my drinks extra cold and the secure lid keeps bugs out!

I honestly love every S'well product I've ever tried, and this one turned out to be no exception. I do acrylic pouring, and the design on this tumbler caught my eye because it has a similar effect. It comes with a removable stainless steel straw with a silicone 'grip' (which holds it in place and upright in the opening in the lid so it doesn't flop all over the place), but the lid also has a slide closure (which you obviously can't close if you're using the straw) as well.First of all, the flaws: it's not spillproof. Definitely not with the straw (as there's always going to be a gap around it), and even with the straw removed and the slide closure closed, it does leak from the opening if it's tipped up. Not a huge issue, but just something to be aware of. Oh, and if you're not used to drinking from metal straws - that thing gets COLD (really cold) if the tumbler is full of a cold/iced drink, and will get really hot if you're using it for a hot drink. It's obvious, but again, something to be aware of that might not instantly occur to you if you haven't used a stainless straw before.Now, onto the good, which is basically 'everything else'. Like I mentioned, the tumbler has a really eye-catching design, first of all. It's comfortable to hold thanks to a slightly textured surface that means it's not 'slippy' and also prevents 'sweat' building up on the surface, and the insulation means that, unlike the straw, the exterior of the tumbler isn't going to get super hot/cold based on its contents. It keeps cold drinks cold (and ice frozen) for a REALLY long time, and will keep a hot drink hot for a good few hours, too. Like most/all insulated containers, it isn't dishwasher-safe, so will need to be washed by hand; unlike some, though, it's very easy to clean.

I filled up with ice water before goin to bed at 9pm last night, it is now 2:45pm the next day and there is still ice in the cup. Still! It’s a beautiful cup and works wonderfully. I also love the straw that is included, it is a metal straw but has a grip thing on it that is flexible. Holds a good amount of liquid on top of being packed with ice. I did accidentally drop it and very little spilled, the lid fits very snug. Highly recommend for the person on the go. It’s not a huge cup and it fits well in car cup holder. I filled it for when I wake during the night and just had to add a little more water this morning to take with me while running errands.

I work from home and typically use plastic tumblers to drink from throughout the day. Whether I'm drinking soda, juice, tea, or water, I love my drinks to be ice cold. In my plastic tumblers the ice seemed to melt rather quickly and drinks didn't stay as cold as I would have liked.This tumbler is a game changer for me. I've had a drink in it now for over an hour and it is still ice cold and not watered down (much of the ice is still remaining). I imagine that if the tumbler would have already been cold then the ice would have melted even less. The spill proof lid is great and the bendable stainless steel straw is also a plus.
