Review on Replacement Extractor Blade Part for Nutribullet 600W, 900W, NB-101B, 900 Pro Series Blenders - Blendin Compatible by Terry West

Should have listened to the bad reviews. I received these and knew right away that it wasn't going to work well. The shank that connects the blade to the rubber teeth on the underside is about half an inch longer, which allows the blade to stick up in the blending position. You can pull and push the blade up and down, in OEM you can't move the blade up and down, there is no play. There are no seals around the base of the blade shaft, allowing liquid to enter the bearings. As others have noted, the blades are dull. The outer rubber pad does not fit properly. I'm sending this back. Do yourself a favor and grab the OEM version from their website.
