Sliding Window Locks (6 Sets), Security Window Locks with Keys, Adjustable Aluminum Sliding Window Stops, Easy Installation Without Drilling, for Vertical and Horizontal Sliding Windows (Silver)

I ordered two sets of these total of 12 and all I installed them today. Myself only had one window left yet to go. It was hard to get to haven’t been able to get to it yet, but I am very pleased with these. I feel secure now, especially in one room. I was kind of concerned, but now that I have them fixed I’m no longer worried. I’m really glad that I found these on here. They are perfect sturdy and easy to install. I highly recommend these for anyone That is in doubt about security now I need to get my doors secured.

I took measurements first to make sure they fit. Attached them on the same day of arrival. They seem sturdy and were easy to attach. Bought them after a neighbor's cat fell out of their window in the eighth floor and died despite a fly screen being attached. I live even higher up. Just want to make sure neither a guest nor maintenance will ever open my windows further than a kitty can get through.

The window locks are sturdy and easy to install. They fit well according to the product specs.

no instuctions in the package, but they were on the product into on amazon. easy to install, fit perfectly into all the windows.

Love these! They work very well for my vertical and horizontal sliding windows. I have a Whole House Fan that needs a couple windows cracked when running it. I never felt comfortable at night when I’m sleeping with windows cracked open. I added these window locks and now I can sleep well while enjoying the coolness of my Whole House Fan! I highly recommend these.

Why did you pick this product vs others?:I'm very happy with this product! Great communication with the seller, quality product, fair price, and fast shipping. I bought these for hotel windows because the guests have broken the plastic ones that were used previously. These are made to last and will not break or be removed easily. I highly recommend.

It works perfectly and each lock has it’s key.

I purchased these bc they had a good price and we need a few more to secure our windows. Unfortunately, these are much larger than the previous ones we purchase so, I will be returning these to keep the look uniform and the smaller profile. From what I can tell the quality looked good and thex can get the job done.
