Would a wireless volume knob for home theaters be worth it?


I've been looking around and cannot find any remote control that has a volume knob on it.  Would having a volume knob that can control my home theater volume be better to using volume buttons?  Or would the cost not be worth it?

At the risk of sounding like an advertisement (I'm trying to find out how many people might be interested in this idea) take a look at this, imagine this being your stereo remote control:

For the most part I think manufacturers have licked the issue of speed of change to up/down buttons. That is, they seem to work well enough for me.


@sfseay very interesting, I wasn't aware of this brand.

Is the remote volume knob better than using a traditional button remote?
