It's a quality product with a good amount of mass to it, which I like. It's also nice that it tapers a bit on the bottom half, making it easier to use in car cup-holders. It's pretty leak-proof, especially compared to other "non-screw on" lids. You're not supposed to use it in a dishwasher, which is fine by me... just calling that out in case that's a drawback for you.
Oh my goodness. THIS MUG is TERRIFIC!!! It's perfect for soda, water, anything you're in the mood to drink. Holds any straw, keeps beverages cold...and best of all, IT IS "SWEAT" PROOF!!!!!!!!!!!! 100 stars.
