Хороший товар

12 December 2014


Батарея хорошая, телефон работает теперь дольше в 2 раза. Качество задней крышки - плохое.


Perfect battery, nice cover

12 November 2014


The battery is perfect. The normal use period of my phone is 4-6 days with one charge. The cover is nice and accurate on the outer side, but I think it's not enough hard. It's bending a bit with some cracking noise on my phone. I don't think this back cover makes the phone waterproof, because the internal seal looks to be misplaced a bit at one part. I think the ergonomy of the phone is better with this battery and back cover. I like it.


Grazie per il prodotto, che soddisfa in pieno le mie esigenze di lunga durata della batteria. grazie ancora Mugen
