Review on 🔪 Enhance Your Blender's Performance with AxPower 2 PACKS 7 FINS Extractor Blades Replacement Part for Ninja Blender - Compatible with Nutri Ninja Auto iQ Models BL642, NN102, BL682, and More by Dennis Long

Be sure to order this if you want your blades to last a month with a single use or two. My girlfriend and I use our Ninja blenders daily for our post-workout smoothies. We are very careful with our things and these blades have NEVER gone into the dishwasher. After less than a month of use, however, the internal seal must have failed as the gross liquid flows THROUGH the spindle that holds the blade through the body. Absolutely disgusting. When I told the seller about this they acted stupid until I cited other reviews with the same issue. Then they apologized and offered to return the money. I'm surprised they still sell this product with such a high failure rate. YMMV, but fair warning.
