I wrote a review earlier and now I'm updating it after I've received a second phone. I'll give the whole story.
I first ordered an iPhone SE that was advertised as "Best" condition and having 85% battery capacity. The battery went from 100 to 1% in 1 hour of use. It also doesn't report battery life accurately, so it may die suddenly when it says 50%. Customer service was very bad too. First, the phone shipped out 1 week late. Secondly, I talked to 2 separate people about this issue and both times, they said they'll look into the issue and get right back to me, and then they forgot about it. So after 3 days of consecutive calls, I finally got a shipping label to return the phone and options to exchange it for a better one (same price, so not really a "deal"). This only occurred after I spoke with the Customer Service Manager, who argued with me for 20 minutes and insinuated they couldn't help me further because I wrote them a 1-star review that accurately described the situation.
Now I have an iPhone 6S and yes, it's better, but still has battery issues. It says it's at 85% capacity, but I need to charge it at noon if I want to use it for the rest of the day. It actually just died when it reported 50% battery. It looks like the saga continues and I'll need to pay to have the battery replaced, which will cost me another $40.
I give them 2 stars because at least they tried to remediate the first situation. However, the phones they sell kind of suck and so does their customer service.
