Looking at the neat wired/wireless 2Way Sensor Bar
got us thinking about the device in general. It's likely that the multiple battery-powered sensor bars on the market reflect an actual consumer interest in removing that extra cord from the Wii setup. We say "likely" and not "obvious" because the existence of products like the "Trauma Center Kit"
is in no way demonstrative of any gamer's interests. We think the idea of losing the wire is neat, but not neat enough to justify the extra cost in batteries. But, then again, our TV/Wii setup is stable and unlikely to be moved around, and the cable is neatly concealed.
Is the cable a problem for you? Are there any other deficiencies in the official sensor bar that would drive you to replace it?
