After failing their first attempt at a padlock, Tapplock stepped up their game and came up with a lock that works. If you remember, it was this time last year when the lock first hit the web outlets, and lock-picks all across YouTube had a field day with it. All it took was a suction cup and a screwdriver to bust open a $100 smart lock. It was shameful. Now, that company is back with version two, and it apparently does what it was designed to do.
