Any reviews for Majesco GBA Wireless adapter?

[Leroy]

My friends and I are trying to get a 4-player Shining Soul II game started and we'd like to bust open Four Swords again but DAMN does playing a 4-player GBA game with those cables suck or what? Nintendo missed a big opportunity by making their wireless adapter not work with older link-cable games.. but I see that Majesco sells one that DOES work with older link-cable games. The question, before we throw $40 down on a set of four, is: do they work well? Any personal thoughts (preferred) or links to reviews would be much appreciated.

It would have been even better if Nintendo made a GBASP with wireless built-in.

Nothing?

Well I found a place that had them for $4 so I guess I'll pick two up and report back with the results.
