Review on PACK 20 Ounce Shaker Bottle Protein by Satish Simone

They're perfect. They have a nice wide opening and are very easy to clean. They don't hold that great protein shake smell that some bottles just don't want to get rid of. Shaker is magic. I used wire ball shakers and large plastic plug shakers. They always left protein powder no matter how I shook them. I didn't have a single piece with me. The shaker's stick shape really works and you don't have to shake it like crazy. That will absolutely be my goal. Oh, and in case you're wondering, they each have their own whisk bar.
