Velux has my expectations for the quality vwieder full justice. Also the design and functionality are excellent. However, I would like to mention yet that but a few, somewhat more in-depth craft skills and appropriate tools should be available for self-assembly and mounting. Drill, angle grinder / metal saw, angle screwdriver / electric screwdriver, etc. Even a little "silvered eye" and patience would not be bad!
Advice to amateur DIY enthusiasts: Read the assembly instructions 3 times through. Up to the last page. Then no one comes into the position of having to cut close to the end again, because a forgotten plastic cap does everything to naught. Nevertheless, Velux again!
