Would recommend!
High quality product for a great price! They are super easy to install, light weight, and very functional for thief prevention. You cannot open the window AT ALL when this is installed!! Size is ideal and it fits all the windows in my house. Package arrived fully sealed, instructions are on the back, and it has a black piece you insert under the metal part for extra precaution.So happy with my purchase!

Perfect product
Easy to use. Very light weight. The size was great. Can’t be seen easy. The removal is just as easy as putting in on the window.

Great Product
This is a great product! You get a lot for your money and they are well made. I gave it only 4 Stars, because the padding that comes with the window locks, that's supposed to go in the window lock when you use it, falls off, making it very difficult to use. However, that wasn't a deal breaker for me and, again, you are getting a lot for your money! I was able to successfully use these on all my windows and now I feel much safer. I would buy these again and I recommend them to others.

Good security measure
These window locks are awesome for added security in the home. They’re easy to put on and easy to remove when needed. They add an extra layer of protection against intruders on top of the regular locks that windows already come with.

Didn't fit my windows.
They looked sturdy. And I was disappointed they didn't fit my windows. Return was easy.

Product Does Not Work
Product does not work. I attached it to my window just like it shows in the picture. I then tried to open the window while it was attached and the window slid right open. So I screwed the lock on tighter. The window still slid open when I tried to open it a second time. When I removed the lock I also noticed that the screw had screwed right through the rubber protector. This product does not work, do not buy it.

Thumb-screw window locks
These window locks are easy to install and reliably keep the window from opening further.
