The processing as such is certainly good, but the attachment is not optimal in every vehicle, since the slats of the ventilation grille are different degrees.
In my case, the item that was delivered with different adapters for TomTom Navi was to "Lippich" just too loose and fell to the Navi downwards.
This should not be a general negative judgment to vent holder from TomTom, but it should allow me to point out that the article probably is not the optimum for each vehicle.
