I paid for 1 day delivery as my current iphone charger gave up on me and I was desperate for a new one. The package of 4 cables arrived but none of them worked. I can only assume they are cheap copies that look like iphone chargers but don't actually charge your phone. DO NOT BUY!!!
These chargers do not work. They do not fit cleanly in the charging port and so do not work properly. You think you've left it charging and return to find it has not charged at all even though it appears to be plugged in.
