Review on ☕ S'well Stainless Steel Traveler - Triple-Layered 16oz Vacuum-Insulated Mug: Keeps Coffee, Tea Cold for 24Hrs and Hot for 12Hrs - BPA-Free, Teakwood by Kate Anderson

I really liked it, but after a couple of weeks one of the rubber rings on the lid came off and is now leaking. It's a mystery. I used it and noticed a black rubber ring in the cup on top of my iced coffee. I had no idea how it got there but figured it must have come from the lid as there are black rubber rings of equal size inside the lid. I was confused as to how it got free and couldn't even figure out exactly where it came from or how to get it back. I put it back in the lid, it was impossible not to stretch it and struggle to get it back in, which made me wonder how it had just come loose and ended up in my drink. When I finally put it in, it turned out that this wasn't an option as now the lid wouldn't unscrew. The rubber ring had to be pulled out of the cover. I had a friend look at it to find out and he was just as confused. Not knowing what to do with the ring, I put it aside. Now the lid is leaking. I want this replaced but Revane's return period has expired. Otherwise I really liked it, but it's not cheap and I don't dare buy another one any time soon.
