Works great on my RPI4 which I use as a home automation server with HomeSeer 3 and Homebridge to turn everything into an Apple Homekit. The fan is a bit noisy, but I don't care, it's in the server rack. Now my Pi is powered by a single ethernet cable! Love it! I designed and printed my own RPI case for use in my server rack. The 1U size is perfect for this POE hat, so the size will fit when it's mounted on the Pi. Search Cults3d for "RASPBERRY PI 4 1U RACK MOUNT"! UPDATE: I sometimes had some glitches with network responses and just blamed it on the Pi itself. I bought a newer network switch and it warned me about TONS (hundreds of thousands of RX errors in a few days) for my raspberry pi. Fix that PoE hat. I bought another brand and will update the review if it works better. I'm surprised I encountered such a problem on the official PoE hat.
