Review on 💪 Powerful PoE HAT for Raspberry Pi 4 - Enhanced Cooling Fan Included by Zoey Vaughn

I had a fan failure on one of these devices and uctronics immediately sent a replacement device. Just thought it might be helpful for anyone interested in their warranty policy. Friendly people Not leaving any feedback on them, I am very happy with the PoE device itself. I'd say my only complaint is that the screws holding the boards together are a bit difficult to tighten, but it's by no means a deal killer. I like the size of these devices. TIP: If the fans are too loud for you, you can install a lower speed external fan (I used a spare fan I had) and point it towards the Pis. Apparently it doesn't take much airflow to keep them in the temperature range that keeps the fans from turning on.
