Great for work!
I take some sort of shaker bottle or a tea/coffee tumbler to work every day. This one beats out all my others. Great quality and sturdy. It's metal but not too heavy. I'm able to toss it in my tote and it doesn't leak... just make sure the top is on tight. I like that it's not see-through. Works great for my protein shakes, water and cold tea. I didn't have any problems with the built-in shaker top, it mixes my powder nicely, but I also add ice to mine. No problems with condensation so it perfect for my desk.  Easy to carry and fits perfect in my car's cupholders. I plan on buying a second one.
