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.

Great bottle for sports, travel or just at home.
This is the only water bottle I have had that does not leak.
The one thing that I would like to see YETI do is include a tool, even if it's just a small piece of plastic that helps you to remove both gaskets from the chug cap lid.
I'm a healthcare provider and have a background in infectious disease and there are several accounts in my area of people who have an ending infections that don't respond antibiotics and finally someone was smart enough to say hey what are you drinking water other things out of. And the isolated and cultured infectious organisms from water bottles.(Not specifically yeti).

Additionally, it would also be great if you had some type of silicone boot for the bottom of the bottles. There are incredibly sensitive to being dented if they're in your backpack and you accidentally put your daypack with a yeti bottle inside the pack down hard and it hits one of the seat rails in the backseat floor of your car on the footwell.

Additionally, I think you guys need to make the gaskets for all of your bottles available on blister cards for people to purchase.

You really sell yourself short by not having these available for purchase,. If someone needs to travel out of the country and their gasket on their bottle breaks and they can't get to a place that stocks another lid they can't even buy a chug cap if they're up in the Himalayas or if they're skiing in Switzerland or trekking in Peru.
You guys claim to be aware of carbon footprints, and not putting more plastic in the environment. Well, stop forcing people to buy another full chug cap when you could just sell the gaskets. You could make it like a tiny keychain tool that has a clear plastic thing that says YETI on it, and just enough of an edge kind of like a bicycle tire iron that would both advertise product and give the user a sense of pride. Otherwise, she ended up with people using the wrong type of knife to dislodge the things. And I can tell you that the upper one of Chug Cap is tough to get off.

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.

I couldn't have had a worse first time purchase experience with Yeti. I have received Yeti products in the past as gifts and enjoyed using those products so I decided to make a first time purchase, however the experience was just terrible. I purchased this product along with the 30 oz travel mug. There were faults with both. On this product, the mouth piece was faulty and did not seal properly. When reaching out to customer support, they repeatedly misinterpreted my emails and were completely unhelpful despite me sending videos to show what the issue was. Next, I called in and they sent me to a warranty link which did not work. After trying multiple times, they had me provide the information in an email to them. It's been over a month and I still haven't been able to use this product that I was looking forward to.

With the 30 oz travel mug, it came without a magnet for the mouthpiece. I reached out to Yeti and customer support and multiple times they sent the wrong item, which I had to correct them each time. They finally sent out a magnet replacement, and when received, it was the wrong one. They ultimately sent out a full mug replacement, which I appreciate, but it took me jumping through so many hoops to get there.

At this moment, I'm still waiting to receive a replacement for my 36oz water bottle. Terrible terrible experience with Yeti.
