Best shaker yet! I've gone through a lot of shakers and have been frustrated by something not working so well on every single one. I really can't believe finally there is something that really works and how many features were packed into a simple shaker.
I love the fact that I can mix anything HOT or COLD! I drink my coffee with protein in the morning...best-looking bottle, especially when I go to meeting very discrete as I don't have to show people my chocolate shake.... I left it in the car for a week and the bottle doesn't smell. When I'm at home I use it for beer...just love the lock mechanism as well-Mark Sullivan
