The prouduct is a monster. It works well so far. The cups are disappointing: 2 plastic only 1 with a handle and a aluminium cup. They are also gigantic! Beware!!! We live in an apartment and constantly wonder what our neighbours think because it is so loud and sounds like a 747 starting up
I am now up to my fourth NutriBullet - I love them! We use it every day for smoothies and protein shakes. It works really well. I have only given it 4 stars because they are so noisy. They need to come with ear muffs or something. Other than how loud it is I would give it a five star!
