Have ordered the product, so that the external hard drive to my Sony Bravia not permanently running just because you want 2 or 3 times a year to record something. If I want to use the time shift function, I take the time to turn on the power. Actually sad that it / is little disks with on-off switch! The 80cm extension I do not need, but oddly enough, the article with the extension incl. P was generally more favorable than the switch solo offered!
