Right out the box, this hand blender is super easy to use. Comfortable to hold and pretty quiet during operation. Love that you can easily control the speed by simply applying pressure to the button. The attachments easily click on. Dishwasher safe parts and easy clean up. I have been using this blender often, mainly the chopper. I chop up herbs and onions, and it does it super fast, plus no more crying while chopping onions. 
This blender is truly one hand operational, with so many functional attachments. My only suggestion, is a safety button. 
I'm definitely pleased with the hand blender.
