I bought the Nutribullet about a month ago. It came with 2 sets of blades. Last week, one of them started smoking!! I looked underneath the attachment and the lubricant was leaking out. I also find that if you leave it blend for more than 30 seconds (the handbook says up to a minute is OK) at a time, the juice gets warm.
Other than that, it definitely does the job and I've been making some great juice for me and my family.
I purchased this because my blender just wasn't cutting it for my protein smoothie and shakes. This is MUCH BETTER - lightweight, and easy to make multiple ones at the same time because we have 2 blades. A+++
I bought this nutribullet and after 3 weeks have noticed my energy level increased and weight loss. It truly does what is says. Grinds fruit and veggies into a smooth drinkable smoothie. Easy to clean and love the fact that it comes with a travel bag so that I can take it with me when I visit mt daughter and grandkids. Could not imagine my life without it, and now I don't have to pay those high prices for custom ordered smoothies at the store. Bought mine on HSN.com while it was on sale and free shipping!!
this machine is not designed to crush solid ice cubes. but if you brake the cubes down to a smaller size, it work just fine. its blends everything very well.
