Zukro50 oz Tumbler With Handle And Straw, Leak Proof Vacuum Insulated Large Stainless Steel Cup with Lid Keeps Cold 30 Hours, Fit in Cup Holder, No Sweat, Dishwasher Safe - Bluewave

Love the size, keeps drink super cold, makes me drink more water... thats the point. LOVE IT!

Cup is huge and doesn't fit on my cars console, but kept my coffee hot for hours and iced tea cold all day!!! Ice was still rattling 7 hours later!!Awesome investment 😃

I've purchased MANY so-called "double-walled" tumblers/cups over the years from different vendors & websites, only to be put in the "garage sale pile". This is the ONLY one that keeps water ice cold (with ice) for hours. Have not tested it for coffee or tea, but if it's as good as keeping water cold, I'm sure it will be suitable for hot drinks. As it's truly double-walled, it's slightly heavy. Great color & great price. Will purchase it again.

Updated Review:I reached out to the company and they were very courteous and understanding. Apparently, I received a faulty cup with my original order because the company sent me a new cup and this one works wonderfully. It does not fit in my cup holder, but it does hold ice and keeps my drink cold. I have had ice and water in the new cup they sent me for nearly 24 hours. The ice is still there and the water is cold.I bought this cup not only because I loved the look of it, but I also believed the claims that it would keep drinks cold for 24 hours, that it was dishwasher safe, that the cup does not leak, and that it would fit in cup holders. I tested this cup for three months to see how it would hold up and perform, although I wish I would have returned it before the deadline. Here are my findings:*This cup absolutely does NOT keep drinks cold for 24 hours. After around 3 hours, the ice in this cup is almost completely melted. Don’t expect to leave this cup freshly filled with iced water on your bedside table and wake up the next morning to a cold sip or water because the water will be warm by the next morning. This is so disappointing because I love to fill up my cup with iced water and not have to worry about it getting warm before I can drink it.*As far is this being dishwasher safe, I have not tested this feature.*This cup does leak. This cup has accidentally tipped over and it is not leakproof as claimed.*This cup does not fit in all cup holders. I am very disappointed by this as well because I always keep a drink with me no matter where I go.It’s really a shame that this cup failed in so many areas because it was not exactly cheap. I will be contacting the seller to see if we can come to a resolution. I will update if anything comes of this. Hopefully, I just received a faulty cup.

Great cup. Use it for work everyday. Carry it with me in the car and golf cart daily. Keeps everything very cold for a long period of time.

Dishwasher safe, seals great, ombré color, stays cool. Perfection at a great price! Idk why ppl waste their money on Yeti or similar “I’m Joe Cool” brands? I’ve had many of water containers in my life and this one makes the most sense for everything you want and need and value. Hands down. Yeti’s lid starts to leak after a few years of use.. and why if they r so fancy… can’t be supportive of sustainable practices… and sell a simple replacement lid… IDK… just sayin’ save ur hard earned paycheck and buy this equally quality of a cup without the hefty price tag!

I love this mug! It does keep keep drinks very cold & ice lasts for hours.This is my second mug from this company.

I ordered this cup in March, and was initially really impressed with how long ice stayed in it before melting.I've used it every single day since I bought it. I use it for iced tea only. Rinsing daily and hand washing with mild dish soap occasionally.During the month of May, it has been getting up to around 80-85° outside, so probably 70 something inside the house.If I fill it up at night, most of the ice will be melted by the time I wake up in the morning. If I fill it during the day, I won't even get 6 hours out of it. I use a LOT of ice too. Like, I fill that bad boy up!I'm in the desert, where it regularly gets 115°. This cup is going to be next to useless once summer hits.I'm bummed because the cup itself is beautiful.I searched Amazon for hours looking for just the right cup within my budget, and this one seemed like a great choice.I bought this cup to replace one that I used for years. The other one kept ice in my cup for days, even during the summer, but it didn't have a handle, so it was awkward to hold.The Good:-Beautiful cup-Love the handle-Perfect size for me-The straw lid, while not spill-PROOF, is certainly spill- resistant, and has already saved me a few times.-Included straws and covers are awesome-Price was great-I like that the lids aren't the screw on kind. Sometimes those kinds of lids are impossible to unscrew.The Bad:-Doesn't keep drinks cold for very long.. Which is kind of the whole point of these cups.-It doesn't reeeeally fit in the cup holders in my car. Ok, it does, but only like the first 1/4" or so. So it's not secure by any means. One wrong bump and it's probably flying out. (See pic for size reference.)
