First - it’s beautiful. I mean just so eye appealing and calming. Second - it’s functional. If I have to be on a call, I just pop the lid on to keep my coffee warm. It does get a little warmer to the touch than some of my porcelain mugs, but I find the handle more ergonomically designed than traditional handles, so that’s a non issue. I have not used the tea strainer yet, but I love the thought that went I to the convenience and mess free nature of the mug. Overall awesome. See photo below with coffee stains to prove use lol. Literally the only mug I’ve used since I got it in the mail 2 weeks ago.
