Question: How does it work?  Are you going to post any pictures of it in use?
Document: They work fantastic...Noone will be able to push that window open unless they break glass. Much more security, and very simple to use.
Very surprised by the ease of use and excellent security, I've searched and searched, actually purchased similar items and absolutely either wrong size for my storm windows and did not work so finally this was exactly what I was looking for. This item will adjust to the right size as advertised. Secures tightly (depends on you) the tighter the better. But keep in mind that in case of emergency this might take a minute or less to release.
One minute can be very critical. I do not recommend to use it as a lock on your ONLY escape window.
Great product works very well to hold window secure makes going away feel secure. Would recommend to anyone who wants the security in their home.
We have a bedroom that is on the end of the HVAC system so it gets very hot in the summer months so we added a portable room AC which requires window exhaust. We were seriously concerned that someone would use this window to gain unauthorized access to our home.These clips fit perfectly & are very secure. We had a 6'5&#34; man use all his might to pry open the window & these locks didn't give at all.
Finally a lock that will work with my windows. Now I can leave the window open a little bit and not have to worry about being robbed!
tried a few other window locks and these do the trick for my windows. as the other reviews say, it can be tricky to make sure something you order online will actually work so i took the lazy route and bought multiple types. i live in an at-ground-level apartment and even though they are small they make me feel better about leaving windows cracked open. buying more of these now!
It worked great, except for the fact that my little boy was able to release the latch and loosen it. I tried to put it at the top of the window, but it wouldn't work with our windows. Instead, I removed the latch screw and replaced it with a regular, flat tip screw of the same size. That let me tighten it with a screw drive so my boy couldn't mess it with it. Only cost $0.13 more and was well worth it.
I bought 2 other window locks that didn't work before I found this one. The others had a thumbscrew that was at an angle and didn't grip the frame. This can open very wide and works perfectly. The lever is much easier to turn and can be folded down when fully adjusted so it keeps a low profile. This grips securely and I'm confident it would deter a thief. It is more expensive than the others, but it works. I will be buying more.
I bought these to help make my children's room a little safer. They look like a great idea, however, the instructions are TERRIBLE. I'm one who can usually figure things out without the instructions - but not these little buggers. The directions are no help whatsoever - I had to look at the picture on the package to figure out where to even start. These DO NOT work on my standard double hung windows.
Answer: no
