This is the 2nd purchase my wife and I have made from Back Market. Both phones we purchased in excellent condition have shown up with 3 days in perfect shape. You wouldn't know by looking at them that they aren't brand new. Highly recommend!!!

The fingerprint recognition is flawed. Unless I moisten my finger and press really hard, the screen rejects my fingerprint. Other than that the phone is fine.
