Installing the product could have been easier, but wasn’t the worse. The plastic protector kept sliding out, turned into a two man job when it could’ve easily been done by one. The product itself does work and prevents the windows from opening. For the price, would recommend.

They did not fit like the picture. The screw barely grabbed onto the sill because the locks sit higher then the picture shows on my sill track. The plastic screw protector falls out as you put the device in place. However, the device does work!

I'm so happy I purchased these for our sliding doors and windows. They are easy to install and are strong enough to keep a sliding door or window from budging, even a little bit. You can choose to install with the bolts facing toward you, or away from you (there are two different tools available depending on which way you want to go). Installing with the bolts away from you would be a bit more secure, but more difficult if you frequently open your windows/doors. Well worth the $.
