The material is in my opinion, very high quality. But the ASSEMBLY! We have two of the day spent a good piece on the door / wall to get, tomorrow it goes to the second round. If you have no specialist has mastered this craft, let rather in the camp are from Amazon! If the bolt would not be processed so high I would have been only one star! And he is definitely not for every door suitable had pretty much "tinkering" and buy more stuff!
