For the past few years we've been looking to expand on  accessories for our KitchenAid Blender. With this kit we're now getting the most usage. I was use to cutting things up myself. Total "simplicity" with assembling and dismantling from blender. Easy cleanup too. No hidden cavities within any part. As for the function of each item: Powerful and Effective. Sturdy product. It's exciting and rewarding having the ability with our KitchenAid blender to grind, shred, slice, mix and blend doing all the work and saving all that time. Wayfair.com headship this very quickly with notifications through email, all along the tracking route, and to your door. A very rewarding experience.
