To be honest, I don't have much trust in electronic devices. Nevertheless, the answer is, I think it's an expensive Apple. For example, it's true that an expensive-selling medical device company makes a profit more expensive, but I think they prefer a more environmentally, friendly and safely method that takes longer to test. In that sense, I think top ranked company of the global multi-national companies is trustful and recall is also quick. Apple is just one of them. Its reason is not their own pros.
