I was looking for a new roller shutter because ours was torn at the floor to ceiling windows. When trying to use a new roller shutter of the old fashioned rewinder me directly broke down, so I came across the offer here. After the first few days is to say that it works. However, the sound is much louder than the neighbor shutters when pulling up and letting down. I suspect it is the cheap material of the belt. It is already clearly inferior to a roller shutter of example. Schellenberg. Therefore, a point deduction.
