But this thread wasn't about whether the true extendeds are worth it, but the OP wanted to know whether the Mugen 1800 is, and the fact is it is not. $30 for the same battery you'd get OEM for $12 is stupid. Mugen and Seidio aren't much if at all better than the chinese batts. Yes the Seidio 3500's are good, but they aren't truly 3500.
There's no reason for brand loyalty, if there was no name "3500mAh" battery than I'm sure it'd be just as good as your beloved Seidios
