Is quieter than when I let down the blinds by hand up under, just ....

.... That the timer ?!
Although you can set a timer to have to get up at the desired time and the programming operation (not rocket science - buttons simultaneously upward with the clock and arrow - that's it). It is the "actual" set time!
Unfortunately, however, the Super Rollo has no Weekend timer, which means that boots up the blinds also on Saturday and Sunday, for example, at 6am in the bedroom / nursery.
Mag not disturb early riser but I love it at least 2x a week to be able to sleep longer ;-) (relative to the blinds in the bedroom, of course)

The instructions are easy to understand, this is no course.
Built as often described, the engine is fast.

Oh something to volume, so clear from the technical side, there are quieter for sure! does no one the blinds silent and to as this device!

Here are some specifications:

Stand-by: 1,35W very high consumption, the competition uses an average of 1W less
Power supply: 24V DC / 29W Very low consumption (of course, lies in the weaker motor)
Torque: MdN = 2,8Nm is ok but not top marks even my 2,2m x 2m blinds almost "get high" but more at the strap lengths, below!

Max. Speed: 34 r / min. This is fast enough, so no waiting until the is up / down driven ;-)
Endzugkraft: 7kg
Max. Tension / initial tension: 25kg
Kurzzbetrieb: 5min. Will probably rich, travels's mostly 2 times a day up and down
Protection class: III
Protection: IP20 So nothing for the bathroom !!!!!
Position accuracy: 5mm
Number of switching times: 2 Yes goofy, as described above. At the weekend there is no mercy
Setting sun control: 2,000 to 20,0000 Lux
Ambient temperature: 0 - 40 degrees
Allowable Belt width: 15mm and 23mm

Belt lengths:
15mm: 5.5m with 1.0 mm belt strength
23mm: 5.5m with 1.0 mm belt strength
23mm: 4.5m with 1.3mm belt strength as it is for large shutters, literally, very close. But whatever the motor is not designed for large shutters. Have it but once tried and found that my balcony blinds - because it is so big - has a different translation, and thus a much longer belt

All in all, for the price a good device but the large standby consumption and the inflexible Timer, can in my opinion, the unit only as "average or not bad" mark.
Therefore 3 stars.
Again thought about it, so there's 4 stars. For this price, you can not ask for more.
