The cable is solidly built and has a #3 lightning bolt on each end of the connector, so don't confuse it with other cheap, low quality cables around the house. Each end of the plug has a hard plastic shell that likely contains microcircuits that protect the electrical current and load. The cable isn't very long, but it's long enough to connect an iPad to a power bank, a MacBook to a 4K TV, and a Galaxy Note to a laptop. The length is comfortable to wear and it comes with a nice plastic Velcro strap for neater packaging when not in use. This cable is only very fast when used with the correct connectors. It's also backwards compatible, so don't worry if it doesn't work with any of the older USB-C models. 80% in less than 30 minutes. Based on my testing, it works even better than the original Apple cable. This does not speed up charging of the charger, it only allows the charger to function as originally designed. I also use it to transfer videos from my smartphone to my laptop and it's pretty fast too, but since my laptop doesn't have Thunderbolt 3 the speed wasn't crazy. In terms of video transmission quality, I don't see a big difference. For me it works like any other regular USB-C cable. With the naked eye, I don't see any noticeable improvement in image quality. If you have Thunderbolt 3 on most of your smart devices and chargers around your house, then this is a great value cable. 24 month warranty, that's great. If there is something wrong with the cable, I hope the manufacturer supports their product. Will be updated in the future if abnormal wear occurs with normal use.
