Remember the term "Snake oil salesman" - Canadian company Tapplock sells a product that claims “unbreakable design” (Unbreakable for less than 2 seconds).

Tapplock claims that unlocking takes just 0.8 seconds unfortunately, it only takes 2 seconds to break-in.

Additionally, they found that the protocol used to grant access to multiple users access couldn’t handle revocation.

 That’s a fancy way of saying that the unlock code transmitted to the lock was identical for every user, which is like having the same password for every account on a server – if one person goes rogue, you can’t lock them out without locking everyone else out, too.
