Keeps Kids Safe - Hardware

This product is EXACTLY what I need to keep the window from opening more than a few inches so none of my young children can climb multiple floors climb/possibly fall onto the ground outside. It offers excellent value for money, a simple metal vise design (the underlying mechanics are grossly underrated in most devices on the market today) and is easy to install. It's worth noting that it slipped a little when I first installed the window if I opened the window hard enough, but I was afraid I'd…

Pros
  • High marks for grip and durability from testers
Cons
  • Vulgarity

There is no "cam-lock " function, but technically it still works on vinyl windows

As mentioned, the "cam-lock" function does not exist due to poor workmanship. This means the lock will not "spin" when you turn the lever after tightening. In fact, he loosened it up a bit by flipping the lever on all 4 locks I received. That being said I was only able to screw it in enough by hand and it holds the window securely. Great design? Yes. Bad performance? Absolutely safe. I can do as someone else mentioned and sharpen the lever cam to actually work, but that seems like a lot of work

Pros
  • Slim design
Cons
  • Weight

Reasonable Security: YES Absolute Security: NO Ideal for home and window air conditioners.

I live in an apartment and I can't drill the window frames without losing my deposit. The Defender U 9809 caught my attention because it installs without drilling, screwing or wall plugs. If you apply them carefully, they will not damage the finish of your windows or frames. If your windows are white, the locks will match perfectly. They allow me to have a window air conditioner that requires the window to be open and closed. Security? You risk breaking vinyl window frames if you tighten the…

Pros
  • Very good price
Cons
  • Security

Better than putting bars on windows as bars cannot be.

I have fitted these to the bedroom windows in the children's rooms. I put 2 on each window (1 on each side). I let about 3 inches of air through but no one can get in. This is better than bars on the windows as the bars cannot be removed in the event of an emergency/fire. I feel much calmer when I go to bed knowing that my children will be there in the morning and no one can enter. I've bought a few more so far. Here is some useful information: I myself use it on double windows. So if you look…

Pros
  • Quality construction
Cons
  • Requires a socket
