I am very disappointed in these. I bought them twice thinking I only got one lemon the first time. It was the same the 2nd time. They last for 2-3 months and that's it. I like the cable itself because it doesn't get tangled, but after 2-3 months they stop charging. π€·ββοΈ Of course I can't return them because the 30-day return period has expired. Buyer Warning.
