    • Would buy again
The added layer of protection with the ease of removal Incase of emergency 👩🍳 😘 They were super easy to install. Worked great. Didn’t cost as much as the alarms and fit every window in our brick home.

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.

    • Extra Level of Safety
These little locking devices are sturdy and very secure when attached to the window slide. We have an alarm system but these add one extra layer of security to all the sliding windows in our home. Good price for the pack of 10.

    • Good, but size will vary by window
I purchased the single screw in locks. The space needed to fit snuggly on my window didn't match the space of the lock. I was still able to screw in the lock and the window did not budge at all. The black buffer wasn't necessary for me and most of them fell out and were lost before I was able to screw the lock to the window. I would purchase this type of lock again and with larger windows I would recommend the style with two bolts for extra security. ... show more

    • One of the worst products I have ever seen...
I purchase these thinking they were the same of what I already have but they are not.... The rubber bumper to protect the windows parts that you clamp onto just falls off.... Then the screw down part will leave a dent/scratch/mark in the aluminum... Completely useless product.
