This gym shaker is well designed and well built for regular use. I am using it for more than a month and almost 6 days a week and till now it gives me properly blended shakes with no issues. It carries comaprtment too. So I bring BCAA mixed in water from home and put protien in second compartment . So during exercise I consumke BCAA and make protien shake in gym only with no issue at all. So getting post workout immiedetly after my sets.
Mixing protien is very simple because of inner design, I t comes with measuring mark too. So simple to mix the proper amount.
