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.

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