The delivery was very quick. The assembly is very easy, if you like me replaces existing manual belt roller. The supplied bracket fits through a plausible combination of various hole spacings directly into the existing holes. Only the plug of the 24V power cable I had to bend the two out of five devices something so that the contact is located. If necessary, I would have the cable soldered. The timing is simple: there is only the time, so you have morning and evening at the right time at the control be to the "Now!" "Now!" enter. This in turn is also very easy, as well as setting the upper and lower switching points. The noise level is - how to read already here - audible in the bedroom I would not install the device, more than as an alarm clock, but in the storage room and office do not mind. All five belt roller were less than 30 minutes replaced by the new electrical appliances. I thought that was impressive and I had not expected. With the sunshine sensors I have not had any experience that I see for my purpose just as a gimmick - if it is going well, if not, no matter. From today's experience, I can (no matter cost, ease of secondary importance, two timer switch points, soundscape) full 5 star awarded the Super Multi Rollo for requirements like mine.
