## Customer Reviews

### ⭐⭐⭐⭐⭐ Works
*by W***Y on June 27, 2025*

Great purchase holds door in place while tugging & pulling it doesn’t move. This give me extra peace of mind & security especially living alone

### ⭐⭐⭐⭐⭐ The Perfect night lock!
*by S***L on June 2, 2025*

I saw this lock advertised on several reels on social media. I have a grandson that's 2 and at the age where he's curious about everything. I worry that he might get out of the house by opening doors. This is the perfect lock to use for that and extra security as a night lock. It was very easy to install and took less than 5 minuets and very affordable!

### ⭐⭐⭐⭐⭐ Does the job well
*by V***O on June 4, 2025*

This locking device is strong and durable. It is simple to install and operate. It definitely makes my basement door much more secure. The only thing I'll mildly complain about is the size. It's quite large and visible. But, that's the cost of having a tough lock. Anything smaller just wouldn't offer the same feeling of security.
