You stick one side of the "lock" onto the glass of the door or window (or any other sliding mechanism that might slide at an inopportune time) so that when the non-stick part is made perpendicular to the glass (by pulling on the pin, which then allows the spring to pull the non-stick half upright), that upright section of will prevent sliding past the point where the 'lock' is mounted.
The idea is that the "lock", when flat, will be thin enough to pass into or through whatever frame or housing holds the sliding element - but will be too tall to do so when the non-stick portion is raised to its perpendicular position. That might not always be the case and if so, the "lock" will either be permanent or not work at all (respectively).
If those two conditions are satisfied, e.g. (1. when flat the thickness of the device does not stop the sliding door/window/etc from opening and 2. when half is made perpendicular, it does) then this will stop a toddler or self movement from sliding the window or door (or what have you) past the point of the "activated" "lock". It will not stop a burglar from simply pushing the sliding door or window with enough force to disengage or simply destroy the "lock".
From the reviews, quality seems hit or miss, and mostly miss when it comes to the pin you need to pull to allow the spring to "activate" the lock (e.g. allow one side to become vertical). There are also complaints re the adhesive, but there are plenty of products (even double stick tape in a pinch) that one might use to overcome that problem.
Intended use appears to be to stop children and honest folks from sliding a door or window past a prescribed point, but this can be very useful for RVing and other applications/activities during which items might inadvertently move or be moved via inertia or wind of the like.
That's what 'cha got here.
And have no clue.

They have sold this product for decades and it is a superior product.
If this works without having to bend down in the corner to unlock, sounds good to me.

Not this brand specifically but I used it for my Patio for almost 4yrs now. It's worked like a charm. Especially great if you have children and you don't want them to open the patio. We put ours way up high so they can't reach it. Make sure you wipe the area with alcohol and let it dry so it adheres extra well. Also don't leave room for burglars to be able to smash the door into it to break it loose.
Except when your kid removes it…
