I've been using them for a long time. And they work great. They are durable and have never cracked. I had an Anker brand. They had a warranty and I was within my warranty when my cable frayed and fell apart and I contacted them 3 times. But they never contacted me or replaced my cable when they should have. And I've given them a lot of things in the past, so I'm done with that. Then I found you! Your best! Thank you for developing a great product that has been a real godsend for charging my Apple products! I carry one with me wherever I go.
