Review on 32oz Huge Cup Set with Flip-Top To-Go Lid, Lid Ring, and Premium Extractor Blade - 7-Piece Blender Cup & Blade Replacement Kit for NutriBullet 600w/900w Blender, includes 2 Rubber Gaskets by Cody Stroop

Blade bearings fail quickly if used once a day Cups and lids are great These blades definitely don't have good bearings, very poor quality The original blade lasted forever , but these new bearings defective after 10 weeks. In all transparency, we use this blender once a day, every day. Perhaps these blades are not designed for continuous use. For others, it might be worth buying a higher quality blender if you blend daily.
