I have 3 Yeti 30 ounce tumblers that I rotate through, using a new one every day. I have noticed that over the years the o- rings on the lids all die with in a few days of each other. It’s like they are talking to each other saying it’s time to annoy Sheri. It always seems to happen during a flare up, when my hands are all but useless. I have to ask for help to get the new one on. I pretty sure that this is the 4th set of o-rings that this has happened to.
John would probably say that this is just the life cycle of the o-ring. That they wear out because you use them so much. Silicone has a limited lifespan. Since you use the same cups every day it’s bound to happen that they wear out together.
Me on the other hand is just think that the o-rings get tired of me and the constant work, so they all decided to quit together. Quitting In mass seems to be a thing these days.
I am sure John’s logical answer is correct, but mine is more fun. What is your take on the o-ring issue?
These are my personal Yeti cups. I bought one to try and liked it so much that I bought a second one. The third was a gift from John and the kids. No endorsement money was accepted. We paid for every cup and replacement o-ring. This is my personal opinion.
