I bought 3 of these locks and have had the lock in place for about 2 weeks now. They seem to be working well. The lock feels well built and looks very professional when installed. The instructions on changing the master code do not seem to work. I tried on all three locks and was unable to get the final success beep. What is worse is that neither the new master code nor the original master code seem to work after that and the lick has to be reset which involves taking the lock off of the door again. Fortunately the instructions for changing user codes works for the master code as well. A few days after buying this lock a black hat video demonstration showing a similar biometric lock being opened with a paper clip was released. This lock does not appear to be affected by that flaw though the key tumblers are not the most secure.
We have ordered 4 of these units for our new home; we wanted the flat black color and these came in that; installation was easy and quality seems to be fine; the knob itself seems a little lightweight but that may be a function of the egg shape; overall we are satisfied with this product.
