I've been using this unit literally every day for a few months now and it's no worse for the wear, still performing and looking like new.
I love the design, especially the mechanism to engage the motor/blender, rather than having a dial or on/off switch (which I've had on other units and has been a point of failure). Also super easy to clean.. I just rise it out and let it dry or wipe down with a towel.
Also, comes with a good amount of accessories, with two large cups, sealable and shippable lids, the screw on blade, and maybe a few other bits and pieces.
Overall, absolutely love this unit and use literally every day. I find it amazing how I can throw in all kinds of healthy stuff and blend it together and have a great tasting smoothie/shake. And, I typically add in some protein power or other "booster" as well. I've not one complaint about this NutriBullet and my only regret is that I did not purchase it sooner. Fantastic Item!
