Review on 💪 Powerful NutriBullet Extractor Blade: Enhanced Mixing for Optimal Blending - Grey, 0.60 lbs by Jason Rosekrans

Good to know this is a genuine manufacturer part restoring performance. It is unfortunate that in the first place it is necessary to replace it with an interval of 6-10 months. After swapping out the pair, I found a no-no pair to avoid and prolong the life of the part: 1. Always make sure there is enough material in the cup for the blades to bite into it. If this is not enough, the knives will turn too fast, the bearings will heat up and bearing grease will escape from below. Alternatively, if you need to grind a small amount of material, use short pulses, shake the container, hum again, etc. 2. Never put warm or hot food in the container. This will cause bearing grease to leak out immediately when you start mixing. Wait for food to cool, or place in refrigerator and bring to room temperature before adding to blender. These warnings are in the manual, but who reads and remembers these things anyway?
