I bought this to make induction recordings and, as I already had a Monacor pickup which worked well, ordered this as a spare. Unfortunately I got an Eagle 171 which is a different size and shape. It is a telephone pickup, just not what is illustrated or described. It works and not really worth returning but they should really just use a generic description rather than a specific brand.
Works fine on most of what I have but not a new Philips home cinema Bluray system (something to do with the "handshake" between the box and the player I am told). I've gone back to switching the HDMI cables. Works great otherwise with older HDMI equipment.
