The housing is made of white plastic and the disc of flat glass. The disc was slightly smeared on both sides. The suction cups are firmly plugged at delivery. If you want to hang the clock on a nail, you see the hevorstehenden suckers. Removing the suckers is very difficult. The included stand can also be used with suction cups, however, the clock then tilts slightly to the back and should not be placed higher than chest level.
Getting started I could the clock, however, because they arrived with loosely dangling pointers. The shortage also could not be by pressing the correct pointer to the pin. The punched hole for the pin was executed simply too small and dirty.
The clock I returned and bought another model from the same manufacturer at Tchibo. There are clean fitted punched pointer.
