These window locks were very easy to install and gave me extra peace of mind right away. They feel sturdy, secure, and work exactly as expected. I like that they allow the windows to stay slightly open for airflow while still keeping them safely locked. The quality is great for the price, and they blend in nicely without looking bulky. Definitely a smart and simple upgrade for added home safety.

Lo he probado en dos ventanas y tiene un cierre muy seguro. Fácil de instalar.

When I received them the first thing that I noticed is they are a little shorter than ones that I had bought in previous. However they still felt very heavy duty and seem to work really well they get really tight on the window frame they are easy to install and each one of them comes with its own key plus one extra. So that's nice. They fit well and stay in place on all of my windows. They function exactly the way they said they should. So far no issues. Removing them is just as easy as putting them on You just need to use the key to take them off. so far from what I can tell for the cost not a bad product.

I ordered this ZRFCXE Window Locks,4 Pack Sliding Window Locks with Key for Vertical & Horizontal Sliding Window to use on a large sliding glass window that needs to be left partially open. I recently installed a couple of amateur radio antennas and did not want to drill through stucco to bring the cables inside. Instead, I ran the cables through a pool noodle and use the pool noodle to seal the window. Obviously, the window needs to be left open to accommodate the width of the pool noodle. It was easy enough to relocate my alarm sensor, but I thought it would be foolish to rely on the alarm and not have a way to securely lock the window. I started at my local big box hardware store. First, I tried a simple thumbscrew equiped lock. It would not fasten down hard enough to prevent the window from opening. The, I tried a lock with a lever. Once again, it would not fasten down hard enough, and in the process of trying to get it tighter, the lock broke into 3 pieces. Honestly, I was not expecting much when I ordered these ZRFCXE locks. I was wrong. These locks work great. They screw down hard enough so that they can't be moved once tightened. The key provided does a great job at tightening the screws, and the small plastic insert really does keep the window frame rail from being damaged by the screws. I ended up using two locks -- one on the bottom rail and one on the top rail. I could not be happier with my purchase!
