Great product
Size: Small Number of Items: 10
I was really surprised at how easy it was to install this product in my windows. Very good quality, and I felt safe immediately after they were installed.
Reviewed in the United States on August 14, 2026 by Annette BardgeThe material is beautiful the color is fine for it, and the fit is perfect. I love this outfit!

Must have for kids and to keep windows closed
Size: Small Number of Items: 10
Must have for kids and to keep the windows from opening from ourside. Very sturdy and easy to install. After installing I trying really hard to get the window to move past it but it was super secure and didn't move at all

Rubber not fastened
Size: Small Number of Items: 10
They work fine. However, I deducted 1 star due to the following: the rubber inside is not secured. This creates a problem when fastener is loosened, since the rubber will fall out and is easy to lose. I am fixing this by using some glue under each of the pieces of rubber, which should resolve this.

Great for vertical windows!
Size: Small Number of Items: 10
I didn't even know there was such a thing! What a great idea, looks so much better than a pipe or a curtain rod! They are fairly snug on my windows ( I got the small ones), but I do feel like they are pretty secure. So far the dog has left them alone.

Only for aluminum window frames
Size: Small Number of Items: 10
The black cushions fall off immediately and these locks don't fit a vinyl window frame. You have to jam them on and its time consuming to wiggle it on and off for every time you have to open/close the window and I'm concerned its going to mar up the window track. These would probably work well if you have aluminum window frames. I wish I could return these. They suck. ... show more

Excellent choice!
Size: Small Number of Items: 10
These work so good! Straight forward easy to use. Locks on tight. We use them to lock our barn door which leads to our downstairs Airbnb. Have used on windows in past. Solid piece! Highly recommend.
