Bests & Worsts Reviews from Amazon

This cable is very attractive, appears durable, and is nice and long. All of my devices see that they are charging when plugged in. However...when I am using my iPad Pro 9.7" while plugged in with this cable, the charging indicator is on, but the battery slowly discharges. I have used many 6-7 foot cables - I consider them consumables - with this device and have never before seen this. I am placing a pretty serious demand on the ipad, with several applications in background, some of which are processor hogs. Charging overnight while the ipad is not in use appears to work, although I have never timed it compared to other cables. I suspect this to be a length issue, since the reason I bought this was to replace another 10 foot long cable which exhibited similar behavior. I thought the cable was just failing, now I'm not so sure. When I use this cable with my iphone 5, it seems able to keep up. I don't think I will be returning it, but being unable to use it while i am working on the ipad is a 2-star deduction for me. Update 11/8/16: Wow. Anker reads these reviews. They saw mine and contacted me to offer a replacement, stating that they believe the cable to be defective. I am very impressed with this customer service. I'll let you know how the replacement works, but this level of service deserves a star promotion all by itself. One note: the cable has a little tag attached with a serial number. Anker will want that number to assist with their quality control. Update 11/15/16: Anker sent me a new cable, and I have been using it for a few days now. The new cable performs flawlessly, and I am comfortable giving back the stars I deducted. As a long time IT guy, I never get excited over cables, have always considered them to be consumables, and occasionally see problems with brand new ones. Full credit to Anker for replacing the one I originally bought and doing it very quickly.
