I purchased my Bullet about a month ago and I like the 900 watts for almonds and kale for my morning shake...problem is there is no washer between the blades and cup and it constantly comes loose and starts leaking everywhere. Simple fix is to provide a washer.
I l;ove, love my NutriBullet ... especially for my morning smoothies to provide me with essential veggies and fruits. Cannot live without! And, on top of it, it's soooo easy to clean.
