After just a few months of night time charging, the Apple watch won't charge. Maybe if the seller sends me a new one for free I'll write a better review.

I've had this display port cable since January 2019, about six months into using it my screen kept turning black out of nowhere. So I had to keep plugging it into another display port on my GPU to get the screen to register. I continued to use it like this for another several months until it kept happening more frequently, now I just switched back to HDMI and have not had any issues for a week. This chord looks pretty but is defective.

Ex Output:
negative

Ex Input:
This was my first time buying vanilla beans but was very surprised with how good they smelled even through the packaging. One of these was plenty to make a syrup with great flavor!

Ex Output:
positive
