The lid over the drinking hole covers the rim, and this makes it healthier and more sanitary than other types of lids, which is the case with 99% of other travel mugs. Both the weight and circumference are very good--it's not too heavy when filled, and tapers down from top to bottom so my small hands can easily hold it. Many other travel mugs in this 20-ounce size are too big around.

Good alternative for a Yeti.

Good alternative for getting a Yeti. I looked at yeti and didn't want to drop $40 so this one is a good alternative. The design is a little flawed with the screw top and the flip up stopper but to save $30 for basically the same thing I am happy with the purchase.
