SideSwipe revolutionizes mixing and virtually eliminates the need to stop your mixer and scrape the bowl to get all your ingredients mixed in. The ORIGINAL spatula mixer blade delivers better results because of its unique alternating silicone fins. The ultra-flexible fins' bi-directional scraping provides a more thoroughly-combined, fluffier end result while maintaining a safe wattage draw. And it mixes your recipes faster, too! SideSwipe is perfect for mixing most everything you use your stand mixer for - cakes, frosting, cookies with chips and nuts, mashed potatoes, creamed butter and much more! Don't be fooled by recent competition that doesn't mix as well or get ingredients from the bottom of the bowl!
