We've been really happy with this blender. It's very powerful, it's easy to use and to clean. Everything about it is sturdy and well made, it's nice not having an additional piece on the bottom to screw on/off to clean.
I bought this a month ago after having two Nutria-Bullets die within a three year span. I mostly use my blendtec to make smoothies. I push smoothie and it shuts down when done. I don't have to use much liquid or concern myself with overloading it or deal with chunks of carrots floating around in it. Everything comes out completely blended. The noise level is not bad and much less than the Nutri-Bullet. I like its sleek design.
I really like the fact the blender has certain types of settings, starts and stops on it's own and does a good job in the end! Though I'm learning that many times i have to pulse things first when making smoothies with frozen fruits otherwise the blade binds down. Also Need to pay attention to make sure it's not vibrating too much before you leave it unattended.
