Have this fan bought in a hardware store (Price 57.95 uro) Unfortunately, I am not at all satisfied with it. When assembling this fan, I realized that some screws were missing, just those who hold the old racing motorbike ceiling mount. According drawing must there be six screws for secure attachment. But there were only three. The engine is quite noisy and are cracking noises. Well, then I saw that this part like so much else is made in China. So botched back from the Far East. Go now back yet.
