NutriBullet 24Oz 24 Oz Ounce Medium Cup with Flip Top replacement part for Nutri Bullet 600W 900W

I purchased the NutriBullet blender a few months ago and have used it almost every day. I recently purchased this second cup with flip-up cap because I enjoy making shakes and smoothies when my friend comes over to watch movies. It's nice being able to make a shake and just hand him the cup straight from the blender and then use the second cup for myself. It's incredibly convenient, uses no other cups, and if what we are making is thick, we don't have to struggle with getting the whole content from the cup and into another container. And if we want a second shake or smoothie, we can immediately reuse the cup to make another one. Again, without having to dirty another cup or glass.
