Good add. Also check the base sits flat - if a rubber foot is missing or uneven shim it or set the blender on a damp dish towel to soak up vibration. Load order matters: liquid first, then soft stuff, hardest or frozen on top, and pulse on low before ramping up. Unplug and gently check for side play in the blade; if the gasket is nicked try flipping or reseating it, and if the blade still wobbles keep blends short and skip ice so it doesn’t get worse.
