Why buy Smartshake Blender 600ml? PHD Review Fantastic idea for a shaker. I have found that the Smartshakers really do make life easier when it comes to training and storing serving size amounts of protein. For example you no longer need to lumber around with a tub of protein as you can store it in the Smartshaker. Furthermore it is very compact and is very well constructed, it fits easily into a gym bag and I have left it upside down, things lent on it and it is still doesnt leak as I have found with many other shakers in the past. based on many factors im giving the Smartshaker a monster Five Star rating.
