Here it is an excellent example of advertisement, how it should be done correctly. Guys that produce cases for iPhones, iPad etc., flew up to a height of 30km and dropped down an iPhone in its protective case g-form Xtreme, which costs $ 40.
The iPhone after falling this huge height survived and continued to function. Well what can you say wrong about the demonstration of the cases possibilities? Video experiment further.
