At the end of the day, this is just a splitter and not worth a huge amount of money. However, it seems solid and should do the job fine.
My gripe was the description. The picture shows two adapters. It also says 2x RCA Phono... Ok, if you read it correctly, it is just describing 2 female to 1 male adapter but be warned, read this correctly (as I didn't) and expect 1 item to be delivered.
