I LOVE my Ninja Foodi Power Nutri Duo soooo very much!  It feels like a professional industrial smoothie maker.  More accurately, if your airplane blew an engine, this one could get you to the ground safely.  The base is heavy and has suction cups to secure it to your counter.  The different programs really do make all the difference in the finished product.  The cups and lids that come with them are a far greater quality than I've experienced with other brands.  Our whole family just loves this machine.  Highly highly recommend!!!
