Solved my slamming door issue

My wooden front door used to slam shut. This concealed spring fixed the problem instantly. It looks invisible which is a huge plus for aesthetics.

Great quality, slight adjustment needed

The build quality feels very premium and German engineering shows. I had to tweak the closing speed slightly, but once set, it works perfectly.

Good value for money

Does exactly what it says. No grooving meant I saved on installation costs. Deducting one star only because the instructions could be clearer.
