I got shaker cups from bodybuilding.com and GNC... sad thing is that they are both screw on and supposedly "leak proof." BS! Lid popped off while in my ice chest... I carry that as my lunchkit to work lol, and it was all over my lunch, dinner, and other meals... Grrr. This isnt the first time either. The bodybuilding.com shaker bottle pops off OFTEN when I shake the protein and milk up...
So my question is, anyone know of a GOOD shaker bottle that is like dishwasher safe that can withstand a good shaking and is truly "leak proof"?
Crowler... why dont you guys come out with one for AI? Good advertisement... and if its leak proof, thats all I'll use!!
