I love it, one of my favorite shaker bottles as it does what it says, it keeps drinks hot/cold for long hours. One thing that could make it better would be if it had small compartment in the bottom of the shaker to store pills/protein powders

Great

Good quality bottle 20oz for my daughter, doesn't have problems with previous shakers. Shipping is good.

Shipped quick

Just received my ice shaker, so far its working great
