Have the hood, since October 2014, it works flawlessly, runs relatively quietly and looks good. But now a lamp was broken, the supplier only prima assembly instruction was provided but no instruction manual etc.. The change is not for the inexperienced recreational craftsmen. You have to look very closely to see that the lamp socket or similar means of a flat screwdriver must be released from the housing. Then it should not be a problem to change the G4. But just a little awkward. Or I was delivered a Monday device, because usually can remove the lamp cover by turning. Why only 4 stars.
