bonne finition du produit mais un peu difficile a faire fonctionner regulierement . mais il peut etre amelioré malgré tout
Muito legal, mas deveria vir um manual explicando como botar para funcionar
Super
The package is not so good . The shaft is loosen from it position and it is difficult to move it to the expecting position ( The shaft should float by the magnet force ) I tried to look for get the feedback for the user manual or guide for how to fix it. But no feed back. I had both of this . It is better than the above .
