The first positive impression by the excellent packaging was confirmed by the product itself. The assembly instruction is excellent even without text; even that necessary for the work tool is attached and the icing of the whole: of all screws in an extra bag an extra copy available. Everything fits, the material quality is blameless for the price. Only one item will not fit in's image: The hinges extract for the keyboard Plateau are greased! This will probably improve the lubricity (with furniture hinges never experienced), but mainly bring fully lubricated finger when mounting. Apart from this "slip" the part is worth the money.
