Horrible product. The lock does not open with 6 of my fingerprints registered. I bought 2 locks thinking they would be as good as the fingerprint lock I bought on Amazon for $19. My Amazon lock works everytime and the Tapplock may work after at least 5 minutes and when it doesn't open I have to go to my car, get my phone and open it from there. I returned one of the unopened locks and got a hard time from customer service eventhough the package was not opened or altered. The site says the battery on the lock lasts up to one year. Wrong! It lasts about one week. I might as well have thrown the $100 in the trash!!
