“This is a great little Hat, Fit's very neatly on the Pi even with the official cooler fitted it's still flush with the top of the USB \ Ethernet Ports.
So far I have not seen any low power warnings.”
“Great to see a PoE hat provide the full 5A and the small form factor is great. Only issue was with the standoffs. They are all female on both sides so that the screws are from both the underside of the pi and the top of the hat. My pis are already attached to a base board so I need standard extension (male-female) type standoffs instead. Would be good to see some extension standoffs included. Double height ones are provided, but I expect providing the female-female ones and male-female ones might serve the same purpose when joined together.”
