I'm a student and have been using apple products for the past 4 years including a MacBook Pro, Ipad, and Iphone. It looks like the quality of apple products is decreasing over the last few years. I just bought the new Iphone 6s yesterday and it seemed to be in good condition until we tested out the calling feature. The person on the other line could hear me clearly however I could not hear them at all. I was extremely disappointed in the quality of this product after having been a loyal apple consumer for years. I will warn my fellow students. I am wasting time to head out to Apple store again.
