Customer Review

Actually, I buy only original batteries basically because I did rather bad experience with replica Batteries. Due to the overwhelmingly positive reviews I decided to give up the NFC function and in exceptional cases to order the Mumbi battery for my Galaxy S4. After a little over two months, the performance of the battery is sobering. He holds no longer than the old battery, I have replaced, so I ordered a new Samsung battery and Mumbi migrates into the drawer.

Update from 19.7 .: Apparently, the company takes the criticism seriously, announces itself immediately and has a free replacement battery pack cleverly, as it seems with some batches are problems. For the extremely sought Customer I increase the rating from one to four stars. I can not say anything because I use this only for three days over the performance of the new battery. Maybe there is still a star.

Upgrade from 1.8 .: The power of the second battery is actually better, so I forgive one point
