This is a very effective product. Although it also functions for high speed video signal, it can also facilitate very fast charging, if you pair it with a certified fast charger. If you want a reliable product, whether it is a cable or a charger, select one that says "USB-IF Certified" or something close to that. It may cost a dollar or two more, but it is worth getting a reliable fast product. Many, many products in these two categories advertise very fast results, but show reviews saying they did nor perform as advertised. Buying a certified (from a 3rd party) gives you more assurance it will live up to its advertised speeds. This products exceeds expectations. On a separate note, the cable is much stiffer than your typical cable, likely due to its ability to pass more power or video through than older generations of cables. If you don't mind the stiffness, you get a very high quality product - the best performing we have found so far.

Very fast and strong

The product looks good and I feel like buying anytime in the future.

Everything about this cable is great except how stiff it actually is. Would have preferred it to be a bit more flexible but perhaps that would have compromised its quality and durability. Use these cables together with NVMe enclosures. Transfers are fast and reliable.

Works for charging and fast data transfers.

Got a lightweight "click" seating both ends of this cable.Feels looser than I prefer, I'm used to a definitive snap retention with constrained wiggle.Using this for an external NVMe enclosure, and T3/USB that had disconnection issues with a prior cable.The price was right for a known legacy brand, with good throughput and so far no dropped connection of my drive.I'll update with any changes.

Works Great!

So I needed a cable for my external hard drives and this one was the one I chose to go with. I bought two and both work well for the price. Fast speeds as shown in the image. Super fast shipping and the quality is what you would want from an old school style healthy cable. A+ and will be looking into other items from this company.
