Ja was soll man großartiges Schreiben, die Türkette macht was sie soll :)

Funzionale senz'altro.

Really good chain, feels very secure and appears to be good quality. The chain is very short though so don't get it if you're wanting to be able to open the door to any great extent.The only annoying thing was that when I ordered this, I did so based on the fact that it's suitable for PVC doors. However, in the description and on one of the questions, it says wooden doors only.So I nearly returned it and ordered a different one, only to see it was more expensive but had the same model name!

Security chain. You can open door partially without letting in possible aggressors.

This product is extremly well made. The chain is however a little bit short, which means depending on how your door frame is situated might mean you cannot look outside the gap between the chain and the door. Not a problem if you have a peep hole. The small chain does have a good benefit, it can help prevent someone from outside undoing the chain. I would recommend this security device. It is far superior to the standard door chains you often see in shops
