That’s basically my point. If your vacuum sealed tumbler says it’s dishwasher safe, the seal failing is on the manufacturer.

But several of mine were too big to fit in the dishwasher. I have a 3L and a 4L that both crapped out after about 6 months of daily use.

The thing is that my dish washer doesn’t have a heating element for drying. It uses a hot water rinse and relies on the moisture condensing on the metal walls. It works surprisingly well.

Yeah, I typically hate brand name stuff, but 100% of my knockoff tumblers and bottles have had their vacuum fail in under a year while my free yeti has been going strong for 5 years.

I actually have to add cold water or ice to be able to drinking it within 2 hours.
