What can I say about the Shaker, well since I already have at least 50 Shaker, so why NEN 51ten? -> Quite simply, the Shaker enjoys longevity, comfort to you if you can take his pre-workout shake, and his post-workout shake can mix afterwards.
Many others have not just that, or at a very low level (does not fit enough pure :) what among us is pretty stupid just for the big guys. These problems are not the Shaker of Induro Pro, the cover holder also makes it even that one not all the time the lid on the face rumflattert while drinking. The screw cap fits tightly and securely, so that can run out nothing during the drive, or if the part rumfliegt in the gym bag :)
A very worthwhile purchase, I have no regrets.
