Its not really about losing faith in the company it is more about surprise in the build quality. As I said above, in February, I was experiencing the issue on the third 5s in a row, eventually by mid February the home button had come loose from its contact and was making the phone unusable. Took it in, they replaced it and now I'm on my fourth 5S. That's great that they will replace it since I had bought the Apple Care + on the phone but it just shouldn't be happening to begin with. If it happened once, I would have thought that I had gotten a dud but it happened on three phones. Three!!
Since then I have not had the problem, which is great, the issue still remains though, that I bought a phone that has a build cost of around $200, sells for around $800 and the main button that you use the most out of the four on the phone seems to have an issue that causes the mechanism to fail. My background is in industrial design so I know that if I design a product that has a specific moving part that will be used more than any other part, I am going to make sure that it works when it is released and continue to work for the average life of the product. A month or two is not the average product life span of a piece of tech as advanced as the iPhone.
