The product is equipped with 900mAh, 1100mAh instead offered as excellent. However, it seems to me anyway left to the imagination in these self-printed labels, what to write on it. So should really again a star plus for honesty give, if it is not yet due to any rules;) The fit of Use S8000 Jet is a little stiff, as has been written elsewhere. Delivery time was flawless. Whether the battery is working, I can not say unfortunately, because my phone apparently has a different defect.
