My wife purchased the Bullet for me because I had to go on a liquid diet. I dreaded this idea of this diet until I started using my Nutribullett. I look forward to my daily smoothie and my health has improved as well.
As an engineer I'm familiar with the various materials that can be used to manufacture a product. NutriBullet appears to be made from high grade urethane plastics. The cost for these plastics is at least x10 greater than the lower cost alternatives. I have run my NutriBullet very hard, yet the bearings are as tight as new. I'm very impressed. It works fantastic!
