Exactly what I needed.
Size: 4 Set Color: Silver-large
Exactly what I needed. These are super easy to install, renter friendly (no holes needed) - you do need two per window as one did not do the trick it just flew off but with two in place, the window stays solidly closed. I wanted these to be able to crack my window open at night while still feeling secure that it could not be opened from the outside. You can determine where on the window to install to either let it be opened a little or not at all. Also easy to remove with included key. However you should probably keep the key close to the window, in the event that you had to open it quickly in an emergency. ... show more

Ok function
Size: 4 Set Color: Silver-large
Ok function. They move a little crooked while tightening which takes away some of the security. They will provide some resistance but, in all honesty, if someone is trying to open the window, these will eventually shake loose. I will say they work ok. Material seems sturdy.
