Works great, especially with the protein packs. Lids locks tight, so no spilling or leaking.

I am loving my shaker bottle. I place a protein pack and 2 tsp of PB2 in my bottle with the whisk ball and everything gets mixed up very well. So happy that I purchased it.

Perfect shaker bottle for my protein shakes. The logo on it is really cool!

I must say I am very impressed on the taste. I even use water and the taste was still good.

Bottle seals well, never have to worry about spillage.
