The first thing I noticed was they didn’t come in the retail box, nor did they have original chargers bundled. That said, the chargers weren’t cheap Chinese ones. That said, in terms of performance, the phones were equal to their retail counterparts — I tested them against the retail versions of the iPhone 6s and the OnePlus 3T. But of course, there were some differences. For example, while the S7 edge looked as good as new, the other two phones had a few marks on the edges (which weren’t noticeable unless you actually took a magnifying glass to it). Plus, especially in the case of the iPhone and S7 edge, you missed a number of accessories provided in the box. Also, by virtue of the original charger being absent, quick charge didn’t work on the OnePlus 3T (but then, one can always buy the original charger from the manufacturer’s website, and yet save a packet).
