Tumbler, 30 Ounces

This is my 4th time purchasing this mug. I absolutely love them. They keep your ice for about 16 hours for cold beverages and about 3 hours worth a hot beverage. They're expensive , but they are definitely WORTH THE MONEY!I bought my 1st. Two set of mugs 3.5 years ago and I am still using them. I use nothing, but this mug. It keeps my pop and water cold ALL DAY.My husband fills both pop and water every morning before he leaves for work every @ around 4a.m. and about 11:30 pm that same night I'll need to add ice.

This cup is great. I left the cup in my car parked in the hot sun filled with ice and juice. When I got back to the car 12 hours later, the cup was still full of ice and the juice did not taste watered down. Keep in mind, this was mid summer. I also did the 24 hour test where I left the cup full of ice and juice for two days. When I checked the cup , there was ice still in the cup. The ice did not melt as much as i thought it would. As far as hot liquids, I don't drink coffee. I will do a review on hot liquids in the near future. My wife was so impressed with the cup I ordered her one. This lives up to its hype.

WE THINK THEY ARE EXELLENT, INFACT THEY WORK JUST LIKE THEY SAID THEY WOULD, JUST LIKE AS SEEN ON TV!!!!!!!! THEY DEFIENTLY LIVE UP TO THEIR WORD!!!!!! BEST INSULATED TUMBLERS ON THE THE MARKET!!!!! I WOULD DEFIENTLY RECOMMEND ROCKY MOUNTAIN TUMBLER TO EVERYONE!!!!! FOR THE PRICE AT $20.00 WITH FREE SHIPPING, YOU CAN'T BEAT IT AND IT LIVES UP TO ITS NAME!!!!!!! THAT'S FANTASTIC!!!!!! I AM EVEN THINKING ABOUT BUYING ONE MORE!!!!!!! : )

Love love this tumbler, l was a little doubtful about keeping cold drinks cold. wow! Even constantly refilling, kept ice for 12 hours and longer! Filling it once kept ice and drink cold all day in very hot wrather. Have a Yetti tumbler but does not keep cold and ice, very disappointed , was told it was the best. I will stand by my mountain ice tumbler. Bought more for gifts and myself only one I really enjoy and give as gifts. The best!!

I find that when I get up in the morning and put alot of ice in it and perhaps a little lemon then fill it with water. I will have good cold ice water until bed time. usually will add a little more water and put the whole thing in the refrigerator and good to start all over the next day. I had purchased the metal straws to go with it and the whole thing is great.

Well It ain't leak proof. Took it to the sink , turned it upside down , it leaked from the spout. Not a lot though. More than just dripping. So be carefulIf it falls over it may spill. The "top" is very secureNo leaks.I drink a lot of Coffee. No it doesn't keep it "Hot" for 12 hours as advertised. But a lot longer. Maybe 2/3 hours. But overall it's beats out my old cup. It was a plastic coffee mug. Oh yeah, it doesn't sweat at all. I haven't tested the "Cold" aspect. Its probably ok. I like the stainless finish.Overall For $12.15. It'll work.

My husband bought one on sale when they first came out. My daughter was shocked at how long they kept drinks ice cold. This is what she wanted for Christmas. It's a great cup. You won't regret the order!

I wish you could buy the original lid’s when these break

Stays hot hot hot or frozen for hours. Best cup on market and I’ve tried thousands Great volume also.Tried to get the nursing union to purchase them in huge quantities

Well worth buying great product
