Since it was very tricky, I would like to describe the times ...
The old system had Clipse with really good Tesa adhesive dots, which can be easy to pull out to a tab. This kept bombproof and the clip system was better because you could just unclip the rail. Well, now it works like this:
1. It is a plastic rail while with 5 Velcro strips. Cut the rail to the extent that the instructions required window width plus 3 cm each on both side - you can be guided by the blind rails -> ok
2. Attach Velcro strips to the frame -> bullshit, first the Velcro and the Flauschteile from 5-carriers with scissors cut. Then the course stick to the rail (3 rich possibly from) the press on Velcro, remove the foil and press to the Fixed -> Advantage: The correct position immediately.
3. Carefully loosen, scrape with a tool between the Velcro, otherwise you tear everything off again.
4. The blades attach -> very tricky because the tape does not stick in the track. Two left and right and the other two in the center, overlapping (so you have two in the middle of the open forward). Beautifully straight and parallel, possibly secure with superglue. The other manufacturers can significantly better. Close and press firmly.
5. Again press on the door
6. Cut the bottom roughly, the best naturally straight. Do not come on to the millimeter, because:
7. lower the weights so attach that down is 5mm square and just will. Here I spent an hour until I had such as I wanted (all equally).
8. If everything just hangs then you've worked up carefully.
9. Put the rubber buffer on holding of the 8 a prompt non - use> Kleber
10. Removing I would be staying, the Velcro keeps Bombenfest, also on wood with 3 pads.
Conclusion: Recommend the only conditionally, in detail the system fails totally.
Adhesive force: 5 stars
Function 4 stars (a door is more dense)
Mounting: 2 stars, patience question
Price: too high, 2 stars (Had a time of 8, which was not too bad)
Overall: ok, three stars
EDIT: NOTE !!! The picture here is wrong, it's not the ups and sliding over!
