Robert Irvine Personal Blender with 3 Bottles (RIPB0030) Gray

I have owned this product for several years now. The secret even Robert Irvine does not know is a blender works perfectly without the rubber gaskets provided for the bottles. The plastic parts were formed so perfectly at the factory that no one realized the gaskets were not needed. If you're blending two or three shakes, remove and rinse a blade part between shakes and tighten snugly. P.S. Inspect the upper edge of your bottles to make sure there are no factory mold seems you can see or feel. If there are, just cut them with a razor and you're good to go.

The rubber part that meets the other part to spin blade was shredding each other. All you can smell was burning rubber. It was bad. Take it off and the rubber was shredded and so was the plastic part where it met. Only used one time.
