OK yall, I had completely given up on blenders after many failed, just worthless units. This unit is beyond belief, and worth every penny. The blender base offers suction, for good grip on the counter. The top locks into place, and has a push button for release.
 Now one of the many beauties, once the dial is pushed on you can choose the setting, for example smoothie, cookie dough etc. The unit then processes the contents according to setting, which is amazing to me how precise it is. The system sets say 60 seconds for smoothie, then pulses, stops, and pulses again. 
I have not yet tried the cookie dough, but very excited to use all the attachments provided. 
Overall must buy!
