After 2 months, I am still happy with my (182% comparing to normal) Mugen 2400 mAh battery.

Just yesterday used GPS tracking and web access (Mappero) for constant 6 hours and there were no possibility to charge from wall outlets during that time. With normal factory battery this would not have been possible.

This thread has typo in the subject line?

Also there is the thread with more info and usage graphs.:
