24oz Stainless Steel Black Protein Drink Shaker Bottle with Powder Compartment, by Athletic Works

The bottle is so wide that it does not fit in my cupholder. It is hard to hold with one hand. The lid does seal, but the pop open top spout is very hard to close.

This shaker bottle is so cute, and I love the fact that it's stainless steel. That is where my positive review ends. I never even got to use my shaker bottle for my protein coffee because as soon as I went to wash it (in the sink, not even in the dishwasher like it says you can) I quickly saw a major design flaw. I wash my protein shakers by putting a little soap and warm water in the cup, add the shaker ball, close the lid, and shake. Soapy water came flying out of the lid/cup seal as soon as I started shaking. At first I just thought I hadn't closed the lid tightly enough, or maybe I hadn't screwed it on all the way. Nope, after checking multiple times I realized that it didn't matter how tight I tightened the lid it was still going to leak. I am glad that I figured this out with soapy water instead of my protein coffee. Long story short- don't even bother buying this. It sucks.
