I bought this Yeti for my husband because he is a courier driver in Osoyoos, BC. One of the hottest places in Canada in the summer. It is not uncommon to see weeks close to +40C or more. Being a driver he is in and out of the hot truck all day and the AC is pointless. He has measured the heat in the cab of the truck to be +45C and higher. Every other thermos for water we have bought has resulted in the ice melting quickly and he has to drink warm or hot water for the majority of the day. Not with the Yeti!! He put ice in the Yeti in the morning and kept it in the cab of the truck with him while he worked and enjoyed cold, ice water all day! At the end of the day we opened the Yeti to find the ice he put in in the morning still there! We then left the Yeti open on the counter overnight thinking the ice would melt with the lid off, but there was still some left the next morning, even though the lid had been off!

Yes, they are expensive which is why I haven't bought one up to now, but if you need a product that will perform as it promises, get a Yeti!

I love my Rambler 18 oz it keeps my ice coffee perfect all day, however, I've stopped using the optional plastic straw my husband purchased from Yeti. I have found that once the contents are gone if I have let it set a while and forgot to close the black sipping portion of the lid any residual drink that may be left in the straw will spit out. I've three times been showered with coffee when I went to retrieve the Rambler. I'm guessing it's due to a pressure change in the canister. I would still recommend the 18 oz, just not with the straw. I use it everywhere. It can fit inside of my small backpack and I also have a clip which attaches to my back pack and the water bottle. I love the convenience of it being small, and not as heavy as my larger yeti water bottle. It’s just right when your st the pool, quick trip to mall, and by night stand for sipping.

Seriously, this thing is so Heft, so Fire, so Fine, so Quality, I expect it will survive any fracas from Global Warming, Asteroid Impact to The Götterdämmerung. I Absolutely Love My YETI 64 oz Water Bottle. It was a splurge for me, and I am glad I choose to treat myself. I consider this an investment. I have been a Water-Holic all my life. I don't like to be without water. I have a sturdy 36 oz plastic reusable but decided it was time to go Higher Tech and buy a bigger bottle, with Awesome Reviews. This one meets my needs. Sturdy as all get out. Tight seals. No funny taste. Holds cold longer than you'd think. Easy clean. Heavy when full, but not awkwardly so. I expect to have this for the rest of my life, and when I'm dead, whoever inherits this sexy blue, stainless steel bottle with warranty and replaceable parts will count themselves Lucky! Oh, and I even love the colour! Thank you!

I recently purchased a YETI water bottle with high expectations, given its reputation for durability and performance. Unfortunately, it has not lived up to its promises in terms of keeping drinks cold. I will fill it with ice and water and within two hours, the ice melts and the water is not cold. I expected better temperature retention from a brand known for its premium insulation. While the build quality is robust and the design is sleek, the lack of effective cooling performance is a significant drawback. For those prioritizing ice-cold beverages, this bottle might not be the best choice. There is a portion of glass on the neck and maybe that’s why it doesn’t live up to the quality of my other Yeti products.
