At first there were many micro heads and heads for iphone in the kit but there were only 3 type C heads in the kit. Not sure if it's a packaging error or what. There is no way to contact the seller either on the Revain website or in the description. I will say the swivel head is really good BUT the cords are flimsy not strong and the magnets are very weak and the heads (connectors or whatever they call it) are very easy to separate the magnet from the swivel. It comes with a cheap little tool to remove the heads from the swivel, but you won't need it at all. I really like that there is a little light at the end of the swivel - it makes it easier to constantly find the end to reconnect to the head, which detaches and stays in your device. I strongly encourage you to keep looking for this cable. not as nice as it seems. I gave it 3 stars for a good swivel and light.
