I waited patiently. So many scammers are out and about. I remain unfearful! I always get my phones from Back Market. I don’t go any other place. My new phone works and looks great. I only get iPhones. I have heard of all the problems androids are having. I had one. That doesn’t mean that they are all bad. The service that I get here is the best that I have had in years. They want satisfied customers. I simply love my new phone! Thanks guys!

The case is very nice and vibrant for its transparency and reflective look. Pretty much, if you want a case that’s just normal and not too crazy and it proceeds your phone, get this one. It’s very simple and easy to put on your phone.

Tbh I wouldn’t know that it was refurbished and not new if I wasn’t the one who bought it. The phone is beautiful, amazing and everything was super easy. The best part was that the phone and the screens came a bit earlier than expected!😁😁

Besides being a work quarters Apple was nice enough to add in the satellite connection for the 13 which was awesome. We received the product in perfect condition even though I think I might have ordered a good or excellent.. I received everything in perfect condition. This item was incredible. It does everything perfectly programmed and I use works great together. The facial connection makes everything work great together. It’s been incredible. At a 10 I’d give it a 20. I got 1000 gigs memory and it’s been awesome as an artist. I like to be able to take a lot of my stuff with me. It’s been great.

This cover and 2 screen protectors are a green choice and they do the job just as well as any fancy new plastic phone cover. If you're buying from Back Market to help save the planet then you MUST buy this cover made of recycled plastic.

I looked up refurbished phones online and Back Market fit my ideology of saving the planet and reusing phones that are ready to be reused. I’m very satisfied with my product and even got a compliment on my phone case. It feels soft on my hands when I hold it. My daughter just bought her own refurbished phone and loves it as well. Let’s save our planet one phone at a time.

Fits perfectly, with round bouncy corners to protect the edges of your phone! When you use your phones flashlight the edges of the case glow with retracted light which is quite awesome!
