GOOD:--------------*You will receive two 4-foot cables, each with four charging heads.* Braided cables are much easier to manage and move than standard plastic-coated cables. .* Super comfortable. Rather than having 4 different cables occupying 4 different USB ports, or disconnecting and reconnecting cables. BAD: -------------* These cables are for charging only. No data transfer. I don't have high requirements or I'm always in a hurry so I never test the speed so I can't tell you how they compare to other cables in terms of speed. I would think the cable doesn't matter, it's the charging technology in your charger. But I can say that it is very comfortable. Just hook up one near you and you're good to go! When you're sitting at your desk surfing the web drinking coffee and your phone is dead, or one of your kids comes up to you and asks you to charge something. Instead of getting up and fumbling for a cable or unplugging and plugging cords back in, just plug the right head into the device. listed. 5 Stars!
