This mug has a screw-in top with a gasket. No leaks! The bottom is rubberized as is the inside of the handle. The handle can be moved for southpaws. It holds 18 fluid ounces.
Negative Product Points
None as far as I'm concerned.
I feel like I got really lucky with this mug. I was up in Green Bay for the weekend and I was poking around Porto Bello Road which is a coffee roaster/gourmet food shop. They sell a few accessories like cheap grinders, press pots and thermal mugs. I was looking at the Thermos Nissan mug with its $35 price tag when I spotted the Trudeau for $19.95.
The thing I really liked about it was the screw in top with a gasket. I've had enough coffee mugs go flying after a sudden stop to immediately appreciate the virues of a truly leak proof mug.
Basically you turn the top 180 degrees to drink. It works pretty well. The top even has a divot where your nose goes. It works better than I expected and I thought the price was reasonable. I should have bought more.
Nothing to say, really. It's a nice little shop but it has a new owner that's still figuring things out.
