I found this product when looking for a solution to a problem we had with the side opening bathroom window continually blowing wide open as the side of the house seems to create some kind of wind tunnel that made the window virtually unusable. I tried this one as it did not require drilling and didn't need to be messed with every time we open the window.It is ridiculously easy to fit, follow the instructions exactly and you'll find it probably takes you longer to read the 4-5 step instruction diagrams than it does to fit them. It helpfully also comes with spare adhesive strips if you make a mistake or need to remove or reposition it in the future.Once fitted you open the window as normal and it automatically locks in place, stopping it blowing open or closed and also effectively stopping any cats (or kids!) escaping out of the window. To close you need to disengage the lock as you pull the window closed so closing it becomes a two-handed job (it is a smooth process as long as you aligned it correctly per the instructions when fitting). It is also easy to unclip the lock if you ever need to fully open the window.Despite the price of these they are a great design and do exactly what they promised. You still get a good amount of airflow and your windows are secure from being caught in the wind. I was so impressed with my purchased I bought 4 more to lock all the front windows in the house as we have cats that are only allowed out in the back garden. It is great to have all the windows open in the summer without having to worry about escapees, one of our cats now likes to sit with her paws out of the upstairs window and watch the world go by...Whether it is to keep animals in, protect children, or just to stop the wind catching your windows this product has you covered...

Brilliant solutionAbsolutly brilliant, easy to install, we can now open our windows without the worry of the cat falling out.

Easy to install if you follow the instructions. It comes in 2 parts which have to be 'clicked' together. No tools needed and not too unsightly. It has a locking mechanism that is easy to open should the need arise. It also has screw holes incase you want to secure it that way. Otherwise, it's fitted with 'very' 'tape that's seems strong enough for me.I got this for 2 reasons.1. To stop my window blowing when open as its in a wind trap2. To stop my grandchildren from climbing up and fully opening the window.I only gave 4 stars as I've just installed it and need to know if the sticky will last. If not, I'll screw it to the frame.I would recommend this product

Seem really good so far, firm and secure. Reading other reviews I have got a spare in case the summer warmth loosens the glue

I recently installed the child lock window mechanism, and it has given me such peace of mind. The installation was straightforward, and the lock itself is sturdy and well-made. It’s easy to use but secure enough that children can’t open the windows on their own, which is exactly what I was looking for.The design is subtle and doesn’t affect the overall appearance of the window, so it blends in nicely. If you're a parent looking for a simple and effective way to childproof your windows, I highly recommend this product.

These are ok but leave a big mess when you remove them. Got as was in rented and landlord couldn’t fit the locks on the windows straight away and with toddlers wanted to make sure they couldn’t open windows fully. They work but some have broken and when looking to remove them they have left big marks on the windows which I know have to try get off.

Should have bought this years ago. So easy to fit and appears to be quite sturdy to keep the cat inside.

We bought this for a low window in our son's bedroom. The installation was very easy and it sticks well to the frame. It's easy-ish for us parents to unlock when needed and I don't believe that my 4 year old son will be able to unlock it for quite a while. We are very happy with the product and had it for several months now.
