What a phenomenal cable! This cable has surpassed my original Samsung cable in quality and durability. As you can see in my pictures I physically bent the cable to test the strength and was surprised it still worked. It charges my Samsung incredibly fast. It took about 30 minutes to fully charge, give or take. The transfer speed is also fast when you transfer videos from phone to laptop. This is a fantastic cable. I use it daily and it's still holding up really well. I dropped it, I dropped it, and it still works. I prefer this cable to my Samsung which came with my phone. Just because it loads a little faster and better.
