Been looking at this product to try and improve my broadband speed. All the reviews suggest it does actually work.
Out of curiosity, I looked up what it actually does, and it seems just to be a new faceplate to disconnect the now redundant ring wire used with the older style phones before the introduction on touch dialling (who still remembers those

)
Question is could I save myself a tenner and just cut/disconnect/rewire this myself? Doesn't sound that complicated (famous last words).
