My son uses shaker bottles to mix his protein drinks. This is a great large shaker bottle. When he seen it he liked it and used it the first day. It holds 20ozs of liquid. He can now take his protein on the bottom of the container and mix it at the gym and drink it. This is a heavy duty bottle that is very well made with no leaks. The lid features a twist and lock system that keeps liquids safely inside. The shake bottle comes in 4 great colors and is also a great price.
He has been using it every day. He also takes it to work. The Maximum shaker bottle will get a lot of use !!! I received this shaker complimentary in exchange for my unbiased review and opinion. All opinions and words are my own.
