Received two PoE injector in individual package box within good bubblewrap protection. Tested the connection with Extremenetworks wireless AP model AP305C and was able to configure SSID for users to connect internet. Aliexpress was fast with the delivery whereas Extreme Networks required longer duration to ship PoE injector upon order confirmation. Already recommending my friends to order PoE from Aliexpress.
I received 802.3at instead of 802.3af. I didn't expect it, so I'm doubling my happiness !
