Rated 4.1 out of 5 by 7 reviewers.
Rated 3 out of 5 by Cheap plastic I have had this sliding glass door safety latch before. The quality has gone down since my last purchase! In the center is what should be a metal pin which you pull out of unlock the safety mechanism. Well now they are plastic pieces!!!??! I actually broke the plastic pin on the first on out of the two pack!!! But it's easy to install and it does work to keep kids from walking out a sliding glass door. November 19, 2013
Rated 1 out of 5 by Not worth the time and money. Locking pins were broken straight out the package, locks were to high to allow smooth movement of the door. With lock engaged, a good hard yank will shatter the lock into a million bits. March 18, 2014
Rated 5 out of 5 by Bought the product and installed to patio doors I was pleased to discover there were two items in each package. March 10, 2013
Rated 5 out of 5 by greatest security products i've used Easy to install--no tools required and not distracting to the look of my sliding doors. I've also used it on windows as an added protection. April 3, 2012
Rated 5 out of 5 by So easy to install and use! This device is so simple, it's brilliant. Not only does it work as an extra lock on the door to prevent anyone breaking in, but the main reason I bought it was to prevent my children from getting out ! Ideal where you have a pool and need a secure door. October 18, 2011
