I love this nutribullet Ultra!  It making smoothies is so easy with this.  Add your ingredients to the fill line, screw on the top with the blade one it, flip it over and place it one the base.  You twist it to lock into place and once it is secure the push buttons to turn it on appear.  You have two options for blending, automated which will run its course and then shut off or manual, which allows you to control the blending action.  Once done flip the jar over and remove the top.  You are now ready to enjoy a healthy smoothie.  This set comes with 3 blender bottles, 2 with no handle and 1 with a handle, two screw on lids with a flip spout for drinking and the base.  It is easy to take care of and washes uo nicely.  I love the compact size that makes it easy to put away and store.
