Joystar 1pcs 6 FINS Gear Extractor Blades Assembly Works with nutri ninja models: Nutri NinjaProBL450-70/BL456-70/BL451-70/BL454-70 Nutri Ninja

The Replacement 6 FINS Gear Extractor Blades with 32oz cup and spout lid is met with Considerable disappointment among customers who purchased it for use with Nutri Ninja models. A significant number of users reported issues related to compatibility, particularly with the Nutri Ninja Pro BL450 model, which appears to be improperly listed as compatible. One customer noted severe damage resulting from using the extractor, stating that it chewed up the rubber teeth of their blender, resulting in the need for a replacement unit. While some customers acknowledged that the blades resemble the originals and performed adequately once properly engaged, multiple reviews reflect a frustrating experience trying to make the attachment work from the start. One user mentioned that it required excessive force to initiate operation and even then, the performance was hit or miss. The quality of the product seems to compromise the functionality of the original machine, leading to dissatisfaction and wasted money. In sum, while the blades may offer a temporary solution for some models, discrepancies in fit and function especially related to certain Nutri Ninja units are leading to a negative reception among users. This product ultimately fails to deliver reliable compatibility and performance, with many Consumers recommending the search for original equipment instead. **
