Ninja BL480 blender, 9 years old. The blender still works, but it does seem excessively loud. I replaced the blade once last year but with a third party brand off Amazon, which works fine. I’m not sure if it’s so loud because the motor is going bad or not but this thing does still blend and it’s powerful. I have 3 18oz cups and lids, some also third-party but they too work fine.
