Bought one and connected two POE IP devices and only one of them could be seen at a time. I thought the first device was defective so I bought a second one and it worked the same way. Bought several alternative POE splitters that also claimed to be switches and all worked great. I don't know why this model doesn't work with my devices, so I sent it back. That does not work. Also emailed the manufacturer and got no response so that was the last straw.
