I use them to power and provide ethernet for Chromecast audio washers and for a Pi Zero (Pi0) with a working pihole. I had no problems with the devices and the installation was very easy. The cable tie holds two devices together (e.g. POE and Pi0). The POE device is lightweight and the connections are strong. A great idea. Good product. I will keep them for a few more weeks and then buy more. To update. I have 6 of these now. 5 on Chromecast Audios, one on pi0 running our home DNS. They work great. 5 of them work in mode 1 (single POE Ethernet), one of them (CCA) works in mode 2 (Ethernet + Power over USB).
