“I was using my original pi 3 power supply but found it kept failing as the connection between the adaptor and board was flimsy and insecure causing one sd card failure during installation due to loss of power, with the Pi 4 power supply all my issues have been resolved, the connection is snug and secure no more power warning icon on the screen. I would recommend this product.”
“Yes, I'm sure you can buy things advertising these specs for less... but why not spend just a LITTLE more for a power supply that you KNOW is going to deliver all the power promised, "clean" power? It has a well made cable. Nicely boxed. If making a gift to someone getting started, it is Just Nicer, not least for having the Pi branding, etc.”
