BABYGO® Window Restrictor – Child Safety Lock for UPVC, Wooden, Metal & Aluminium Windows | Self-Adhesive, No Tools or Drilling | Easy Fit Child Window Lock, White

Excellent product which is easy to install. I’ve got 3 now which are durable and stable to put up with my cats leaning against the windows. Perfect for letting in some fresh air at night without the risk of them escaping the upper floors.

I purchased this item to go on window in young daughter’s bedroom. I found the item easy to install. The instructions are simple to follow. It took less than 5 minutes to install. The size of the item works well with my windows but measure up before buying to ensure it will fit! Item feels decent quality and it has worked on my windows and allows the window to only open so far before then locking into place. If my daughter ever got close to the window, she wouldn’t be able to push it further open or disconnect the item in any way. It feels sturdy on the window frame. I do feel a bit safer knowing it’s on the window. This item protects one side of the window. You would need to purchase more to protect both sides. But, we just keep one side permanently locked and then open the protected side safely. The adhesion to window frame feels good and I don’t think my daughter would be able to pull it off. Not before us noticing anyway! Based on current use, it’s something I would recommend to other parents.

Love the product. Brought two as I have 2 kittens and have been unable to have the windows open in this heat. Took 5 minutes to fit they open enough to let air circulate. Be careful with the profile of some windows. As although they may fit, it may not let you open them to the full extent.

So handy. Stick one part to fram and other part to window. Easy to fit and easy to unlock when nessacery

Excellent safety product for homes with young children. It was very easy to install, holds securely, and gives me peace of mind knowing my child cannot fully open the window. No drilling was needed, and it works exactly as described. Highly recommended for parents.

Absolutely useless. Stuck it to the window and to the side. Left it. Then gave it a try and it comes unstuck. I have absolutely no idea what the point of this is.

Excellent product. Easy to fit. Purchased for two lady friends with adventurous cats. No more escapes!!

Bought this because our bedroom window was too easy to open and our cat kept going on the window sill. Very easy to install and does exactly what we need it to do.

Broke within two months. Clip jammed and so couldn’t open/close the window
