Amazon.com Product Description:
Every business and property owner knows how difficult it can be to keep security tight, especially when several individuals require their own access. It's easy for anyone to replicate keys, and it's expensive to constantly change locks. The Digital Peripheral Solutions QSB180 Q-See Fingerprint Doorlock with Keypad is designed for any home, office or room where security and peace of mind is a must. With three ways to unlock -- fingerprint only, fingerprint and PIN, or key -- the QSB180 is a versatile security option that even children can use. It is great for a house keeper, guest or anyone that you'd rather not give a key to. With a single latch made of zinc alloy, this lock is easy to install and requires no special software. Up to 30 fingerprints at a time can be enrolled directly on the lock. It is powered by four AA batteries (not included) that last about a year with normal operation.

Rating : - easily installed; works fine
Unlike the other reviewer, I did not receive drills, etc but just the lock and some extra screws. Installation was easy and it has been working well so far (at least for the last few days).
