Apparently at CES 2010 Bob Plaschke CEO of Sonimtech told reporter Dan Simmons that the Sonim XP1 was completely unbreakable and that it had been subjected to every possible stress test. He even went so far as to tell Dan “If you find a way to break it, we’re going to give you a free phone.”
After submerging the phone in a fish tank to no avail, Dan repeatedly smashed the phone on the sharp corner of the tank. On the third smash the screen cracked and Bob Plaschke was shocked. “You’ve actually broken the phone. That’s impressive. That’s absolutely impressive.” After that he probably asked Dan where he would like his very strong but not unbreakable phone sent.
