Like the prior reviewer, I have tried in frustration to use the cheap, freebie mixers from supplement orders. All suffered from two problems; leaks (protein shake on your gym shirts/shorts - Arrgh.) and poor mixing of whey protein and other powders.
This shaker bottle has a tight fitting screw on lid, and a securely closing pop-open top that have never leaked, not once.
I thought that the stainless steel "blender ball" seemed like a gimmick but it WORKS GREAT, mixing even hard-to-mix supps like BCAAs well. Whey powder, Gatorade powder and such are a breeze. Just make sure you have an ounce or two of liquid on the bottom before adding powder and you're set.
