Great shaker bottle with non-slip grips and bottom.
I needed a new shaker bottle and decided to give this one a try.  I've used this for a few days now and I am very satisfied with my purchase.  It's leakproof, which is good considering I throw it in my gym bag.  The blender ball works just as well as any other blender ball out there.  I really like the non-slip grip that they put on the sides (finger grove area) and the bottom of the bottle.  It really helps with not dropping the bottle when there is condensation all over it.  My only wish is that there was a ring or a loop or something on the bottle to make it a little easier to hold.
