This review is based on a two week period. As a person who makes green smoothies daily I would recommend this blender. I was always pushed towards the VitaMix and Blendtec models but this works probably just as well. I believe the difference between those models is that this one is 1hp and the other brands were 3hp. Needless to say, this thing is powerful. There have not been any vegetables that I have had any problems blending yet. Kale, celery, herbs, mango, orange, apple, etc. All of it is blended quickly with no chunks on the low setting. Surprisingly the high setting has been overkill. I do chop the ingredients before putting them into the blender though to make it easier but so far no problems. Also, the operation of the device is simple. Plug it in, turn to low or high then turn it off. If there are any negatives it would be the noise and the size of the carafe. Seems smaller but the plastic it's made out of makes it much lighter then the glass ones I'm used to. I have not made any soups so I do not know how it handles hot ingredients. Overall, very happy with the purchase. The only reason I did not give 5 stars is I have not used the VitaMix or Blendtec brands and do not know how they compare.
