Honestly, this is a great mug. I've had a lot of different ones and 2 things stand out to me about this: The quality and the thickness. The glass is very finely crafted and even along the handle where it has what you might call "seams", they are extremely well made. The glass is also significantly thick, especially at the base. So far I've had no issues with any sort of "sweating" or condensation on the outside of the glass, even with a piping hot or cold drink.
The right way to perk up your morning.
