Query: Opti-glow cable review

This opti cable broke two of my cable box opti source inputs, careful when installing and uninstalling. The head is not shaped like a normal Opti, at first i thought it might not fit, but it did really snug and it broke my opti inputs on both cable boxes and my new Samsung 3D tv. I guess you get what you pay for. It does work however, but you must tape it on to get it to connect since it broke my inputs.
