The terminal makes a valued and stable impression. It is meticulously crafted and holds the shutter bombproof in place. The fuse is my opinion, however, not meant for the daily profit, but rather more for backup while vacationing, etc. (Shutters down, window, security mount, close Fenstzer -> would tell me honestly stressful :-P). Should anyone looking for a permanent backup, from the same manufacturer, there is also a mounting solution: 16002 Schellenberg (Schellenberg 16002 blinds automatic backup) as holiday securing ideal, I can confidently recommend it!
Another tip: Replace the fuse near the top on the window / shutters. I tried the shutters to pull up while the backup was mounted. By the claws bites firmly securing and (but need not) can, was a burglary attempt / accidental ovens because it simply forgot to scratch the window frame. Sits securing high up they scratched for a not so much, on the other hand it blocked immediately after the first millimeters / centimeters.
Then I only wish all buyers: May never be used it ;-)
