## Customer Reviews

### ⭐⭐⭐⭐⭐ Works perfectly! Feel safe now
*by M***F on August 8, 2023*

The media could not be loaded. I was hesitant to buy this but I'm so happy that I did. It's super easy to use and really does a great job securing the front door. Apparently, dead bolts are now easy to break into so I felt better knowing that my front door has a 2nd locking mechanism. I just ordered two more for my two back doors. I highly recommend 👌

### ⭐⭐⭐⭐⭐ Very sturdy and easy to use
*by F***H on February 7, 2020*

The management of our apartment building recently had the brilliant idea of removing the latches from everyone's doors. There is no way that I'm sleeping at night with just a dead bolt lock for security. Over 95% of dead bolt locks in America can be opened in a minute with a Bump Key. This device is easy to use. You don't need any tools or special knowledge. You just place it on the floor under your door handle and tighten it. My door didn't budge no matter how hard I pulled on it. This product is a winner.

### ⭐⭐⭐ Looks good and may work better on flat surfaces
*by M***O on June 27, 2024*

This barely works for me as my door has a little threshold raiser. But don’t all door kinda do? Would’ve been better if leg that’s screws into this were an inch or two longer.I’m afraid this would do very little if pushed hard but make a little noise.
