Window Locks, 10 Pack for Vertical and Horizontal Windows, Sliding Window Locks, Adjustable Aluminum Stoppers, No-Drill Install, Fits Tracks up to 3/16" Wide

Easy to set up and works perfectly. Great added security for peace of mind on a first floor apartment

Great product but unfortunately they didn’t fit the windows in which they were intended for. However , they were stillput to good use. Durable, and gave me a peace of mind knowing my littles will be safe.

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.

Brain-piercing audio alarm will indeed wake you, and everyone else within a five mile radius, should someone be silly enough to open the door or window you have this humble alarm affixed to. Peace of mind? Yeah, it works as long as the batteries are fresh. Value for money? I'd say the doggone thing works about as well as a shrieking harpy stuck with a cattle prod would, so yes on that. Ease of use? Yeah, it's about as easy to use as riding a bicycle (probably actually easier than that since bicycles have confusing things like gears and wheels on them just to mess with mens' minds): you slop it onto the surface, flip the switch to "brain piercingly loud shriek" and you're solid. The chime is cute, if you dig cutesie little "welcome to my shop" type of alerts but the other alarm setting is sufficient to stun a police dog or blast the eardrums of any attempted thief.

Good, sturdy product. I easily replaced a broken lock like this one in just minutes. All fixed!

It works pretty decently. The rubber pieces that came with my package were a bit too short for my windows, but I made some on my own and it worked. When I received my package, the package was already opened. It came as if it had been used and the packaging to it was in bad condition. It makes me definitely feel safer about my windows though.

Work great on my windows with window ac units and gives me peace of mind being able to lock them in place and keep out someone who may attempt getting in or stealing my units. Easy to use and install. Worth the price for 10 of them. Good design. I've used these style locks in the past and have always been happy with them.

These totally suck - they offer no security whatsoever! After they are installed and tightened down the screws loosen up within a few minutes rendering them completely useless.By the time I realized they didn't work it was too late to return them for a refund - so now I'm stuck with $15 worth of crap.
