## Customer Reviews

### ⭐⭐⭐⭐⭐ Buying this again.
*by S***S on February 3, 2026*

Pretty easy to instal and has worked flawlessly for over a year. Good purchase.

### ⭐⭐⭐⭐⭐ There may be a flaw in the handle.
*by A***R on May 16, 2026*

The one I received was defective. It says reversible but it was not.

### ⭐⭐⭐⭐ it works at normal temp less than 90 degrees
*by T***Y on August 29, 2024*

I gave this 4 stars for the sellers, but 3 stars for the product. The lock does not work if the temp real hot, 90 degrees outside (if uses as an exterior lock). I must give the company who sells it props, for standing behind their product. Why? After installing the lock for 1 year, I decided to now install the batteries. Only to find that the electronic features did not work. I contacted the company, and they send me a replacement. The replacement also failed a few days later. Then I notice it only works when the weather was cooler.
