I will take uncovered photos later tonight, or early tomorrow, just got home, long day, and the case is a particularly well crafted one, meaning it's actually a bit of work to open. Not sure what you mean by talk-time, actually talking on the phone? Less than an hour. Using the internet and whatnot, maybe a dozen or less. The previous owners use is unknown sorry.

Damn case off for like 5 minutes and screen smudgy as a momugga
I looked extensively into all this phone nonsense when I was looking to buy (because there was a lot of confusion) and here's the deal:
"Apple Unlocked" iPhone 5s are only unlocked on GSM networks, AT&T, T-Mobile, Simple Talk, etc. Will not work on Sprint, Verizon, MetroPCS or any CDMA carrier (although there are rumors that you can pester them enough to accept a foreign ESN on to their network, or Flash the phone but lose LTE access).
The main draw to this phone would be if you would want to use the Verizon network. Typically Verizon phones go for slightly more as it is the network with the best 4G LTE coverage in the US currently.
Verizon/Sprint/CDMA iPhone 5 phones can be unlocked (and are typically, the latest software update from Verizon unlocks phones by default afaik) for any GSM network as well as their particular CDMA network (but not cross CDMA due to the frequencies they are designed for). Hence a Verizon phone can be used on a GSM network, but not a Sprint network. Take a look at the phones being peddled as "Global Phones" (because the rest of the world uses GSM).
As to "Similar item", I've looked at Gazelle before, their products in "Good condition" come with potentially scratched screen, dings, who knows what (no pictures provided), and does not come with anything, no battery, usb cable, box, etc. Not to mention 16gb and 32gb are apples to oranges comparison. Definitely a good bargain basement buy, but not particularly relevant as a link.
