No different than someone buying better tires to replace the ones that came with the car. No different than spending $500+ on a new smartphone, just to find the earpieces aren’t nearly as convenient or comfortable as an aftermarket brand, the Tamperla™ stick is the first aftermarket blender stick created to fit many of the blenders across the world. Created over several years by a college student and former Vitamix demonstrator, the patent-pending Tamperla™ Blender stick is finally available for purchase! Blender Sticks is a non-commercial site, set-up to inform you on the different types of Blender Sticks available, it’s attributes, and where you can buy them.
