extends overall length of HDMI cable. No noticeable signal loss, have to secure both cables as there is no real restraint holding each into this adapter, Used it for two 25 foot cables under the living room floor.
Needed to connect my tablet to my tv and this made it happen. I can usually find the cables I need on Overstock and not have to pay those inflated prices. Check Overstock first, there's a good chance they'll have what you're looking for.
