Top Amazon Reviews


  • Excellent
Excellent so much easier than carrying a key or trying to remember a code
Reviewed in the United States on November 20, 2018 by Virginia S

  • Not durable. Lasted 10 days
I bought the lock and within 10 days of normal use it broke. Not what you would expect when purchasing an expensive lock.
