Not to say briefly zuuu. As already noted my Vorrezensenten, disengages the pin holding the lever, when ringing. Back to the top I've always noticed yet and reingeschoben him again. But when I then not do it once the pin and consequently the lever has adopted immediately. Thus, the bell is useless. It is a complete mystery to me why a lot of the bell evaluate as good. Please first take a couple of months in use !!! Just because it can easily be mounted, must far be awarded 5 stars!
