I have been so impressed with my Nutribullet full size blender. I was previously using the personal size model. The full size has been a great upgrade. I love that you still have the ability to use the personal size cups as well as the larger one for bigger batches. It has awesome power..has chewed through everything we have thrown at it. This blender has not left the counter since we got it.  It has been used at least every other day since we got it. Works equally well for smoothies as it does for the occasional milkshake :)
