I ordered 4 of these from a drop a year ago. Exactly one year later they have all failed. No signs of kinks, bends, cuts, or frays. These all look and feel like new, but connections will fail.
FYI these are quite possibly the worst cables I have ever purchased.
The quality of the cable itself is excellent, however, while plugged into my Google Pixel 2 it says charging but it doesn't actually charge. I thought it may have been my phone so I gave it to a friend who has a Galaxy, same thing with his.
These cables are either really slow or I got a bad one!
