Just say NO! Unfortunate purchase and no returns allowed.
"Horribly disappointed in both the product and their customer service. This is listed as a "travel mug" but doesn't retain heat and doesn't seal. From the time I filled it from my local coffee shop - with fresh brewed drip coffee, brewed on demand - until I arrived at my office 15 mins later it was less than lukewarm. I contacted Customer Service and was told once a mug is used it cannot be returned or exchanged. I'll never purchase from Ello again and have told everyone I know, in person and on every possible platform available, to avoid the brand."
