I don't think, (though i can't be sure) that lag is the main problem with modern wireless meese. Worst thing that happens is that at any inconvenient moment you have to change batteries, or worse, recharge the thing. I have my g500 since BF2. Tried to poison it with beer, champagne, rum and cigarette ashes, but it kept tracking in all that mess. Congratsssh! You just bought yourself my favorite battle weapon. I hope you can find peace with all the killing.
