Mixes protein powder and boost very easily with only about 30 seconds of shaking. No lumps mixed throughly. No noise while shaking as this bottle does not use a wire ball to blend powder and liguid. Has a removable plastic mixing screen. Works great.

Works GREAT!

I went to visit my daughter and had the stuff to make my protein shakes but no way to mix it up to get the lumps out. I put in an order at the local Walmart when I saw they had this available. I could mix it up and drink from the shaker's spout. It has ounces and metric measurements on the side which was perfect. I've continued using it every day even though I'm back home. It is made well and doesn't leak, as long as you have the drink hole plug securely in place. That's another reason I love this is I can close the drink hole and shake it up again if the shake contents start to thicken or separate. I just add water when I'm done which helps clean it out. Photo with the rinse water is all I have right now.

Nice but a few issues...

The size, construction, and functionality of the cup is good. However, the key items that are not good about it is the "O" ring that keeps flopping out of the lid that ensures the zero leakage. It is cheap and ill fitting to the cup lid. You have to stop and hassle with trying to get it back on. Additionally the grip band on the top is also loose. Bad specs on these two key items to what would otherwise be an excellent cup.
