Review on Ailun Micro USB Cable 10ft 3Pack - High Speed 2.0 USB A Male to Micro USB Charging Cable for Android Phones and Tablets, Nylon Braided for Enhanced Durability, BlackGrey - Compatible with Wall and Car Chargers by Matt Spencer

One of the chargers, a micro USB part, is bent so badly that nothing will work unless you hold it it in a certain way. So check them all out when you first get them to make sure they're good. We didn't, and now it's too late and we only have two good ones left.
