Battery that does not hold charge more than a few hours of constant use. (Computer does charge and works flawlessly when plugged in with charger, but I would not recommend for extended use when there is no power outlet available. Meaning, the battery does not hold a charge as well as a brand new one, which is to be expected with age and use.)
There are some marks on the screen. I tried to show them in the pictures. I personally do not feel it affects use, as when the screen is lit, they are unnoticeable to me.
Lastly, my cat is an a*hole (what cat isn't?), and has chewed on the charger a bit. How he did this without electrocuting himself is beyond me, but there are some chew marks on the charger cord. However, I found it hasn't affected its functioning or ability to re-charge.

Feel free to message with any questions. I will ship by next business day after payment is received. Thank you!

The MacBook Pro "Core i5" 2.9 13-Inch (Early 2015 Retina Display) features a 14 nm "Broadwell" 2.9 GHz Intel "Core i5" processor (5287U), with dual independent processor "cores" on a single silicon chip, a 3 MB shared level 3 cache, 8 GB of onboard 1866 MHz LPDDR3 SDRAM (which could be upgraded to 16 GB at the time of purchase, but cannot be upgraded later), 512 GB of 4 Lane PCIe-based flash storage (standard prior to October 27, 2016), and an integrated Intel Iris Graphics 6100 graphics processor that shares memory with the system. It also has an integrated 720p FaceTime HD webcam, and a high-resolution LED-backlit 13.3" widescreen 2560x1600 (227 ppi) "Retina" display in a case that weighs just less than 3.5 pounds (1.58 kg). It does not have an internal optical drive.

Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.0, two USB 3.0 ports, two "Thunderbolt 2" ports, an HDMI port, an audio in/out port, and an SDXC card slot.

In addition, this model has a backlit keyboard, a clever haptic-capable "Force Touch" trackpad and an internal, sealed battery.
