With so much hype around NutriBullet Pro, I decided to purchase it for myself. Sadly, after just one use, I am so disappointed with it. Whether I pour water just below or right uo to the max line, it always over spills! Even when I just add a banana, some protein powder and water, it fails to grind everything to a smooth consistency...I'm left with lumpy bits every time! It's pretty useless for the price. Don't waste your money on this.
