This guy bills himself as an inventor of useless products, and he's generally right on the mark, but this time he may actually be on to something.

Ha! A second mouse is a lot cheaper than a 3D printer. Still, pretty clever...

It may actually be a marketable product, though, in which case there'd be no need for a 3D setup.

That is truly an incredible invention. However, this article, which directly references that YouTube video, makes an astonishing revelation: after placing the mouse in the amazing cradle while charging, the inventor found out the mouse does not work. Apparently Apple's design precludes the mouse from operating while charging, regardless of position. Hence, the mandatory and inoperable upside-down nature of the charging Magic Mouse.

Thanks for that. It's interesting that the thing appears to work in the inventor's video.

And, ironically, if one was able to charge and use simultaneously, they'd be back to having a wired mouse. Personally, I have yet to find that charging is an issue. The charge lasts an awfully long time and, when it needs to be renewed, just leave it charging overnight.
