Zero Degree Stainless Steel Tumbler with Lid, Double Wall Vacuum Insulated Travel Mug for Hot and Cold Drink (20oz)

Absolutely love. The cover is well fitting and no leaking around the edges, no seams inside for stuff to gunk up and with the cover on it will keep your drink seriously hot for a very long time. I actually have to remove the cover to let it cool down enough that I can drink it! I timed it and gave up at 2 hours after I made my tea it was still way to hot to do more than micro sip, off with the cover until I could drink it, then put it back on so it would stay hot enough until I finished drinking it, totally worked. I use this whether I go out or not, and I am using it everyday. It cleans so easy, and stainless is sanitary so that relief is added to it. I now have a 2nd one for my daughter to use after she has seen how awesome mine is. This is an excellent purchase. I have used this for ‘travel’, in the car, and had no problems with it, other than the removing the cover so my drink would cool down enough so I could just drink it, which I think and excellent problem to have. —————- Update -1-10-20 The lids started cracking a few months in, as of today one has an all the way through crack from the mouth piece to opposite lid. Very upset as these are a favorite. I thought I could just replace the lids, zero degrees does not seem to have replacement lids except for 30 ounce size and mine is 20 ounce Y model. ? There is no lid size measurements to check and other co’s lid sizes doesn’t say inside or outside diameter. If anyone has replaced their 20 oz Y model lids, please let me know which ones fit. I like the sipper lid, not yeti. Thanks

Not sure if I just got a one in a million kind of mug, but my cup of coffee stays hot for 10 hours and its awesome. Though the bottom exterior becomes ice cold. It doesn't effect the coffee in any way and seems to stay hot forever, just might startle a few if they're not prepared for it. It gets really cold on the outside of it.

Keeps coffee hot and iced tea cold for about 3-4 hours minimum. Still at least warm/cool after 5-6 hours.

Ok here's the low down.... I'm sold on these tumblers. They keep your drinks cold even in the coldest of weather for hours on end. It came with 2 diferent tops, 1 that had a spill proof top and one that wasnt. However, although it is advertised that the straw will fit in center hole provided on the spill proof top, it does NOT. So these are not spill proof when using any staw. I've already knocked it over and spilled a very hot liquid all over. I ABSOLUTELY would reccomend these and am replacing all of my cups with these. Great buy!! (Pictures of before and after dishwasher) *** After they went through the dishwasher for the first time, they are loosing the outer couting and have begun to change color in some areas. I've added pictures. Both tumblers have done this. I only took 1 star because this doesn't change the working status of the cup. Only cosmetics. But still, if these have to be hand washed it should say so. I hand washed before I made my first review and used. A little upset.

I bought 2 of these to take on vacation to an all inclusive resort. Even under the Jamaican sun and 94 to 99 degree heat, the drinks stayed cold for hours. I could leave this by my lounge chair and have a swim and come back to a still frozen drink. LOVE LOVE LOVE this mug.

The tumblers themselves are fine, but the lids barely make a seal. Coffee stays hot as it should, so that's not a problem, but I don't like how easily the lid comes off. I'll go with a different brand next time.

My husband needed some kind of vessel to keep water cool during his days at work. I searched many different options before landing on this one. It has many of the benefits of the overly high-priced containers without breaking the gift bank. He loves it. "I can put ice in it at night and it's still there in the morning," he said this morning. And he also likes the very slightly nubby exterior, which is easier to hold than some of the slick-sided ones. So thank you! Your product helped make Christmas gift-giving successful. :D

I love love this cup. It was given to me from a friend and I liked it so much that I ordered one for my son and he truly enjoyed it. We used it for our protein drink with ice and 6 hours later there is still ice in it, not even the CONTIGO cup would do that for me. We have not tried it with hot drink. As I am writing this review I am about to order another one for my younger son!!!

Same as the pic
