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.

Don't wash the knockoffs in a dishwasher, the cheaper seals can't handle the expansion and contraction. If you're not willing to hand wash you need to buy quality which isn't necessarily Yeti but you'll need to do research.

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.

Top rack with the dryer heat off is much easier on them if you do

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.
