A 4.7-inch Retina HD display with 3D Touch. 7000 Series aluminum and stronger cover glass. An A9 chip with 64-bit desktop-class architecture. 12MP iSight camera with Live Photos. Touch ID. Faster LTE and Wi-Fi. Long battery life. And iOS 9 and iCloud. All in a smooth continuous unibody design.
Most of the reviews I read on this product were great, so I had set my expectations fairly high, and I was not disappointed. It was packaged very nicely and looked to be in perfect condition. Battery seems to be perfectly fine. Definitely worth purchasing.
