## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by S***G on May 22, 2025*

Good security upgrade to my porch door in my apartment. I like that you can tighten (extend) it with a wrench to very snuggly keep the door closed/secure.

### ⭐⭐⭐⭐⭐ Great addition to have
*by W***E on May 3, 2025*

When we moved into our apartment all we had is a little wooden stick to keep our sliding door secure. Got this for more security to have when the wooden sticks fails and our sliding door slides open. It is adjustable and you can figure out the size you need to make your doors secure. I didn't have difficulty putting it together,

### ⭐⭐⭐⭐⭐ Safety Bar
*by A***R on May 7, 2025*

This is simple to put together and I am pretty sure it will do the job from someone opening the window unless they break the window. I am 66 years young and I am happy with purchase and I bought another one for the other window.
