Daily snapshot data starts accumulating once the scheduler runs — for now this is interpolated from the agency's first/last dates.

What is this? A metal part in some window or smoke/heat vents may not be strong enough. It could break and let the window or vent fall.

What's happening? A weak gear in the moving part might break under pressure. This could let a heavy window or vent drop suddenly.

Does this affect me? If you have a window or vent with this brand in Germany, Estonia, or Slovenia, it could be unsafe.

What should I do? Stop using the window or vent. Ask a builder or your landlord to check it. Talk to a professional before using it again.
