IMPORTANT SENSATIONALLY

The MEAL WORKS (ie the "heads" with the blades) NEVER give in the dishwasher !!!
Because the sealing ring of plastic in the heat of the dishwasher dilates (expands), then easily (often imperceptible, but mostly you fumelt him back because you think no evil) out-comes and will inevitably at the next meal-speed shredded is! !!!
I have the whole device so have to buy, but fortunately fit the plastic cups - but now I have two engines.
ABSOLUT child secure, is completely impossible bad use to operate it.
Otherwise, unbreakable and the plastic shells (grinding vessels) are properly dishwasher suitable (also often).
For single household ideal - in family and serious use I would recommend larger device. (But the engine is super-strong and not overheated -. It is only cumbersome for large quantities, such as cake-baking)
