    really good, but I picked the excellent condition for it and had hit marks as if it was dropped and not repaired very good but if you want a 100% geranty that it's gonna be good get premium condition 👍👍👍👍👍👍👍

    I love my phone now. The only thing I wish the website would show is why they rate the phone "fair, good, ans excellent" quality. I wasn't really sure how to expect the phone. I got good condition and it has scratches but I still love it.

    Phone is perfect, the only issued I had was that it was shipped with an aftermarket charger that didn't work with the device. Any easy fix and was still cheaper than new.
