### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent lock so far
  

*by T***L on Reviewed in the United States on October 20, 2024*

No issues for the last 8 months or so. Works well. Never use the app other than setting up the fingerprints

### ⭐ 1.0 out of 5 stars







  
  
    E-Waste, Doesnt Charge and Doesnt Work
  

*by M***A on Reviewed in the United States on October 15, 2024*

It broke after a couple months, it wont charge, it was always super finicky, the app was super bad and would take super long and half the time fail to connect to the lock. I would have always have to use my fingerprint a couple times for it to work. Sometimes it just wouldn't work, none of the 10 fingers I put worked and luckily I was always able to go through the app to get my door unlocked. Waste of money and now it doesn't even work.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Overall, a Nice Door Knob
  

*by A***M on Reviewed in the United States on June 22, 2024*

The installation process for the knob was very straightforward, and setting up the fingerprints was quite simple as well. However, I wasn't particularly impressed with the accompanying app, and I was disappointed to find that no charging cable was included in the package. Initially, I had trouble getting the knob to charge with the cables I had on hand.I reached out to DINSTECH, and they responded promptly. They informed me that the knob requires a USB A - Type C cable and not a fast charging cable. Once I used the correct cable, the knob charged without any issues. Despite the initial hiccup, I'm pleased with the product overall and plan to purchase a couple more!
