I bought my automatic roller shutter drives from the company Rademacher about a year ago and am still very happy with it. I missed now only the sun / -Dämmerungs sensors for. This I ordered some time ago and immediately mounted. It is simply gorgeous when the shutter - even if I am not at home - in the sunshine on automatically and be driven off. With the purchase of the Rademacher-products and of course the delivery I am very satisfied and can only recommend this company. Therefore, the five stars!
