This blender is the best blender I have ever owned! It is so strong, it blends so fast and clean up is a breeze. I used to buy Vitamix, but never again! 
I think Kitchenaid makes the best appliances, too. I used to buy Kitchenaid and was happy with them and several years ago I rebuilt my house and put in Subzero & Wolf appliances, as I have to replace them, I will replace them with Kitchenaid again! I have had more trouble with Subzero than I would have room to share here.
