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.
Do not be fooled into purchase the higher end HDMI cables, as long as the specs are what you want, buy the least expensive cables from a reputable dealer, and you can't go wrong. As with this purchase, I have no complaints or issues, and would and have bought more.
