Love the mug, the only thing I’m unsure about it my lid doesn’t screw down completely flush on one side. There are no leaks but aesthetically it would be nice it there was no gap.
I LOVE this cup and use it every morning. I bought it assuming it would be good for transport/outings but now it's replaced my bugs. My coffee stays hot, it's cozy in my hands and the lip of the cup is smooth.
I like the design but it leaks. I put water inside and shook the mug to test the water seal and water leaked. I dried it and tried again, same problem. Both my wife and mine.
Did not realize the entire vessel is not porcelain lined. Keeps the coffee hot but still imparts that funky stainless steel taste due to the stainless edge and rim. Yuck.
I gave the mug 5 stars because it is everything promised by the company. It's extremely well made and keeps beverages piping hot. I purchased the 16 oz. Carter Wide Mug. It's too big. I make tea in mine, and the volume is too much for one tea. The whole thermos just seems too large. I think I would have preferred the 12 oz. Wide Mug. Again, I gave the mug 5 stars because the mug is great! These are just my personal preferences.
