I bought the phone as a gift for my partner and we only set it up yesterday. It's a lovely phone (one up from my own) and I really like the protective case that came with it. The protective screen went on perfectly and my partner is very happy with it. Beats the crappy thing he had before, but don't tell him I said that.

Je suis décu de la protection qui possède un léger défaut et qui ne fit pas bien avec mon Ihpone 13. Il y a une légère bosse au niveau en haut à gauche.

It was a perfect fit, it has already proved it worth a couple of times, so definitely very good value for money.

This case is perfect. it enables me to charge wirelessly whilst still protecting my phone. The glass screen protectors were pretty easy to install and went on smoothly with no bubbles. The case I chose was clear which allows me to see the colour of the phone beneath. The silicone gel case fits snuggly with ample protection around the corners and along the edges as well as being slightly raised offering further protection to the screen too.

It fitted beautifully with the iphone I bought from Back Market. But that is in the final return process and I've bought another iphone elsewhere. Not tried to fit it to this one yet, but can't see any reason why it won't be fine.

Always a bit stressed about not wanting to break my phone, am so glad I could just buy a cool looking case and screen protector with a couple of clicks. Took less than a minute to put on too!

Buying technology is not my favourite thing so it was a delight to find Back Market. The process was transparent and simple. The ethics of the company are commendable in recycling technology. I am delighted with my refurbished phone and the service I received. Back Market will be my provider of choice for the future. Keep up the good work!
