4PCS Kids Window Door Cable Restrictor Lock Child Baby Safety Security Wire Catch with Keys for Home Public and Commercial Applications-White

They're great, can't fault them at all. Study enough to hold back an indoor cat trying to play with the birds and allows us to let in a bit more air.They were really easy to install, goes quicker if you have two people (one to hold it in place while you put in the first screw in each piece) but can be done by one person quite easily.

Great product to better restrict windows

The product was ok. My only complaint is that it could do with white screw caps

Can't complete a full review as they are not yet fitted. No instructions included in the box.

We purchased these for our upstairs windows as a dual purpose to prevent people accessing from outside and also from a safety perspective for our children. They were easy to install directly onto the uPVC frames. The lock is the same for each unit so that makes it easy to open when required.Only slight negative was the quality of the white protective plastic shield which protected the main cable seemed a bit short and was exposed. This doesnt effect the functionality more so the look of the product.Overall really happy and great value for money.

They work as expected and seem to be pretty good quality.

Good little product. Easy to fit, keeps the little ones from accidentally leaning out of any windows. Can be unlocked if you want to open your window fully but of course you need the key. Pretty safe and recommended from out experience fitting and using these. Price not bad either.

We used these for our wide opening windows to make them child safe. The self-tapping screws went into our white UPVC windows quickly and effectively. All fitted in minutes as long as you mark out where you want them to go and check the measurements for safely (10 cm maximum opening for children is recommended). We had to have one side higher to make the opening smaller but all done and look good.
