[quote name='TopSpot123']Still laggy with Rock band 2, but new games that are built to support it are fine, i.e. Rock band 3 should have virtually no lag. Mic sensitivity may be a problem though, but it just depends on how serious you are about your singing scores. I recommend getting it and trying it yourself, if you can spare $20.[/QUOTE]
Dunno if it's lag or crappy wireless mic, but on RB2 I do a lot better with the regular RB mic. The wireless mic on Lips works just as well as the corded one though.
