I would give a negative 5 stars if I could. These chargers stopped working after only a couple of weeks. We ordered four chargers, and they all one by one stopped working. They show on our phones as charging, yet our phones die while they have been connected to the chargers for more than 30 minutes. The first two weeks with the cords were great. They making charging different types of devices extreamly easy. If they hadn't stop working, we would have happily told more people to try them, though now we will be telling people not to waste their money, since the company won't honor their warranty without making their customers do the job of an employee and try to help them figure out where the charger failed. It is NOT the customers job to find the error with your products.
