Advantages and disadvantages of roof window shutters?

Hello everyone,
We are currently considering having blinds installed on our Velux GPU top-hung roof windows afterwards. Until recently, I was convinced that, of course, the Velux SSL solar blinds should be installed. Now our neighbor (who has the same roof windows) has made me somewhat uncertain. Our neighbor had the Heim and Haus roof window solar blinds installed.

He said that the Hamburg blinds are mounted directly on the window and that you can completely open the window and also swing it, so the blind can sometimes be cleaned from the inside. According to Velux support, however, the Hamburg blinds can no longer be swung because the motor would block with Hamburg.
With Velux, the blinds are mounted on the window itself, so the window with the deployed blind can only be opened about 20 cm (according to Velux support). However, if the blind is rolled up, you can open and also swing the window as usual.
I have read in forums on the internet that there are also blinds from, for example, Roto.

My question is now:
Do you perhaps have roof window blinds? Did you install them yourselves or have them installed?
Why did you choose these exact blinds?
If you don’t have roof window blinds but have nevertheless dealt with the matter or are familiar with it, your opinion/experience is also gladly welcome.

Thank you very much. Best regards

We also considered blinds, but besides the green ones you mentioned, for me as a NoGo, there is also "dark or light," respectively dark with sun protection or light without sun protection. We now have sun protection awnings and interior blinds. Overall, it is cheaper and, in my opinion, the better option.

I installed the solar shutters from Velus on Velux windows myself. It went smoothly. We previously had sun awnings outside and blackout curtains inside. But that's no comparison to shutters. I would do it the same way again.

For us, they were purely bedrooms, so it was also okay if the shutter froze shut in winter and stayed closed during the day.

We replaced 2 Velux wooden windows with Hamburg plastic windows with roller shutters 3 years ago. Velux opened via a central tilt hinge, Hamburg opens fully. Now you can also stand at the open window. The roller shutters work perfectly and reliably. They darken excellently and are a blessing thermally in summer (we have our bedroom under the roof). Much better than an interior blackout. As for the price, you can almost negotiate as you please, the Hamburg guys have a huge margin.

Did you have to climb onto the roof for the installation or could it be done from the inside?

Came from the inside. You just mustn't drop the screwdriver ...
