I've looked long after such bamboo blinds. The selection is great and the quality is usually something to be desired. In this Rollo the sun shines a little by little. It makes the atmosphere but that's why so comfortable and the room is not just dark. There are a few very pleasant and beautiful sunshine. The attachment with the supplied hacking is very easy and the operation is very simple. In brief: quality and handling get from me 100% satisfaction !!!!!!!
