Looks like there aren't enough negative mentions yet.
I bought this adapter harness along with an aftermarket radio to install into my 2005 Subaru Impreza. This adapter is a must for installing any radio. I double checked all the wire connections on the adapter harness and all the wires matches to the radio harness. I connected and soldered all the wires and wrapped with electrical tape and the radio was ready for install.
I would recommend this to a friend
