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.

Easy to fit and fairly robust.

I have used these for years.. Peace of mind when leaving the house easy to put the the extra chain latch in place when leaving the House.. Then easy to insert the Key to remove when returning.. Dual purpose Chain on when at Home and Chain on when out.. Good solid construction. Peace of Mind.

It’s a good tough chain, but the screws that go with are cheap weak ones. Use your own if you don’t want them to break off.

This seems very good and strong.

Easy to fit and simple to use
