[pianotech] Pianodisc silent systems

[David Love]

Can anyone who has experience comment on the upside/downside of installing
these systems on a grand piano (Baldwin F)?  I'm not actually going to
install it, I would hire someone (it's out my purview), but a customer of
mine has a noise issue in practicing late at night and is considering
something like this.
