I liked this mug so much that I bought another when I found it at a similarly reduced price on the Mothership. I don’t need my drink to be hot for 12 hours nor cold for 18. Just long enough for me to drink what’s in my mug, thank you. I can finish my hot or cold beverage at my leisure before much temperature change. I also like the non-slip bottom. Today, I bought three more - one more for me & two to give to friends. Woot’s mug is less than half price, by the way.
Nah, it’s not a YETI, but we ain’t fancy folks! 
This does just fine!
I haven’t put them in the dishwasher like some have (and complained about the result). Because I have an extra, I can handwash one & it has time to dry while I use the other.
I like mine for tea & I used it quite a bit for coffee. Haven’t used it lately because it doesn’t fit under the portafilter of my newer espresso machine. 
Breville if it matters to anyone. Sure, I could pour contents from the coffee cups I brew in and dump into here, but why wash two mugs?
