The lid of this bottle deteriorated after less than two years so it no longer seals fully and leaks which seems to be a common problem from the reviews. I reached out to the Yeti warranty program as they provide a five year warranty for the bottle. It has been over a month since I first reached out to them and I still have not received a new lid or a new bottle as Yeti promised. Yeti originally confirmed that I would receive a new lid but it never shipped. So I called Yeti a couple of times over a two week period. Every time Yeti told me that the lid was out of stock and they had no idea when the lid would be in stock. After my calls, Yeti then offered to provide me with an exchange that required me to ship my bottle back to them and Yeti would then ship me a new bottle as soon as they received my old bottle. Yeti received my bottle and have not shipped me a new bottle. I called Yeti again and now they claim I could receive the new bottle in 2 to 3 weeks despite originally telling me that the item would be shipped as soon as they received my old bottle. Again, no one could confirm when this new bottle would ship. So now I am out of the money I paid for this product and I no longer have the product as I shipped it back to Yeti as they promised an exchange. I am now stuck hoping Yeti honours their exchange and provides me with the new water bottle as promised. This has been the most frustrating experience.

I was also told that I would be unable to leave a review as I did not receive a special link when I bought the bottle from their website. Despite their website stating "To write a product review, head on over to the product page and scroll down until you see "Write a Review.", there is no option to leave a review on the website and I was told that I could not leave a review without receiving this special link. I did not receive the email providing this link after I bought the bottle and I was only provided with a link to leave a review after speaking with their escalation team. So from my understanding, you cannot leave a review unless you buy the water bottle through the website and even then you need to make sure Yeti sends you an email with this special link. Overall, I had a very disappointing and frustrating experience with customer service and the warranty program that has still not resolved, and I would not buy a Yeti product again.

The chug cap was apparently designed only for carrying upright, and the numerous reviews must have only tested it that way. Because if you drive anywhere and lay it down, you need to tighten the cap quite a bit to not leak. On the second use, I couldn't unscrew the narrow-spout base... Even channel locks couldn't provide enough grip and leverage to bust it loose, and my vice doesn't open quite wide enough. I eventually got it off with my biggest pipe wrench, which of course marred the rubber a fair bit. The chug cap itself unscrews easily by its handle, but the base needs a heavily serrated perimeter (like a classic Nalgene bottle) or hex/octagon shape to have something to grip onto. The base gets tightened by tightening the cap, so it's all-or-nothing. It's a very shortsighted design for such a premium priced product. Functionally, the 36 oz Yeti doesn't insulate nearly as well as my smaller Hydroflask, but it's much better than a non-insulated Nalgene. Trying to contact Yeti about the issue is equally frustrating, as all their contact options lead to dead ends and even the Chat With Us link doesn't go anywhere or open anything. They utilize the contact page as a shameful means of selling more product.

Ordered a custom version of this at a discount. The order went through, and then I got an email saying that they no longer had the product I ordered. So I ordered this one.

Had it for less than a month. Chug cap leaked. Destroyed my Scottish Leather bag and work papers. When I called Yeti to tell them it was leaking, they wanted me to send proof, upload pictures, and treated me like I was lying. I told them to just sent me a postage-paid box, I'd send them back the defective product, and they could send me what I paid for = a product that doesn't leak.

All in all, it was a terrible product and an even worse customer experience. I think that I'm supposed to get a replacement chug cap sometime soon. We'll see. I don't even know that I want this product anymore. The whole experience made me feel taken advantage of, and I feel like I paid for a product only to get terrible customer support when their product wasn't working as advertised. I used to love Yeti products. They used to be extremely high quality. Now I'm not even sure that I feel welcome as a paying customer. In the past year alone, I've ordered 5 Yetis from their website. Don't think I'll be ordering any more.

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.
