Don't play-play with german products... even the cheapest one has very tight safety measure. I just bought a blender. I tried it yesterday night & i thought it was faulty because when i switched it on, it can't run.
Then the next day i returned it. The staff demonstrated to me that there is nothing wrong with it. Everything has to keep tight & in right places, even ...the top lid which i thought it was insignificant. Then, no way you can get injured by blender.
