Rated 3.5 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by such a little thing for so much safety! A must have, especially for those with children. Easy to use, permits you to leave your windows cracked open at night or when away from home to allow fresh air in without worrying about someone opening your windows to get in. Also a great security measure to keep kids in! April 27, 2009
Rated 5.0 out of 5.0 by works great! It works just as it should. It get tightened well, doesn't move around and the window can't be opened unless I take it off. I didn't know when I ordered it online that it comes with two in the bag so I had a nice little surprise when I saw second one! December 10, 2013
Rated 3.0 out of 5.0 by Works But May Not Be All You Need We just added a sunroom with double sliding-glass windows. We bought these after our son opened one of the windows and pushed the screen out. It only fastens to one side of the double windows, however. It wouldn't fit the track on the other side, so we had to put a makeshift block on that side. December 12, 2010
Rated 1.0 out of 5.0 by Dirty item received The product was not heavy duty and was scratched and dirty. It really looked used. I purchased similar products at the store, but needed something heavy duty as advertised on line. However, the product is exactly what they sell in the store, plus shipping cost and was dirty, scratched w/ scuff markes and really appeared used. I could have saved $100% by purchasing at the store directly. Very disappointed April 16, 2013
