My Yeti mug has survived three years of daily commutes. The lid still clicks shut perfectly. That initial sting fades fast when you're not buying overpriced, lukewarm swill.
Right there with you man, that $40 felt brutal at first but now I look at it as cheap. Got a similar one a couple years back, the kind with the push-button lid and ceramic lining inside. Keeps my coffee hot for almost three hours on the morning commute, even in winter. Plus I stopped grabbing those $5 cardboard cups from the cart on the platform, which adds up quick over a month. The lid on mine finally cracked a few weeks ago from dropping it on concrete but honestly it paid for itself ten times over by then. Never going back to disposable cups again.
