When I bought this lock I thought it was great. Reasonable price, and lots of functionality. THe fingerprint usually worked, and the software on the mobile app is good. But then I tried to use the kepad and I had no success. I had 2 of these locks installed, so I tried the kepad on both locks. Only about 1 out of 10 times did the keypad work. I wrote to customer support in China, but they did not write back with anything except a question "Are you using the appp?", which was useless. And there is no live customer service available. So I will be going with another brand!
