I had a problem and took a star off. The first one I got only worked for about 15 minutes. The power supply has failed. I made a quick refund and got a replacement on Amazon. Two days later I got a new one. I used it all day with my Macbook Pro 16 2020. I connected an external drive, a display, a network cable and a USB microphone. Everything worked as expected. My Macbook charged almost as fast as an Apple charger. I'll keep an eye out for any problems with the new PSU.
