• Ninja blenders feature 6 male fins, not 7 or female fins, so ensure your blade matches this design.
• This blade only fits 16oz cups. It is not suitable for 12oz, 18oz, 24oz, or 32oz cups.
• Before using, verify that the 6-fins blade is securely fastened to the blender cup to prevent leaks.
• A gasket is already included inside the blade. The extra rubber gasket in the package is for backup and may have loosened during shipping—ensure it fits snugly.
