good functionality, good security, easy to use, easy to fit, nice product

This door chain is solid, strong and a great security addition to my door. Easy to fit and does exactly what it should.

Works fine so long as you install correctly, do some homework. I watched a couple of you tube videos to aid installation. Comes with zero instructions which is very poor. OK it's easy enough to work it out. As others have said the screws it comes with aren't great. Therefore it's important to drill the right size pilot hole for them. I went with a 2.5mm on frame & 3.0mm in the actual door. Our door is a composite one. Also you need a screwdriver with a good grip & one that is sized for the screws, otherwise you're going to mess up the heads for sure with these screws. It's worth considering getting some quality screws instead. I was prepared for this, but thought I'd try them first. All went well for me. So overall i'm happy. So far. Will see how it goes after we've used it for a while. But seems sturdy & looks fine.

Excellent quality and safety for your home very easy to do

As with many others, I used my own shorter flat head screws for the larger plate. Sturdy and good value chain although I do wish it were longer or you could have some spare to decide how long you want it. For the price though, can’t complain.
