I ordered this battery because previously 3 (!) Original batteries were broke within a year. This battery should be my last attempt - and he succeeded! It is definitely worth the money and has saved me from a mobile phone new purchase. Four stars are there because it has to load a long time to really be full. It has not always 3h to charge the phone. On the other hand this leaves a very long-lasting battery and less than 20% is far down. Fits perfectly into the device, since no trouble with the battery more - it can not be more, but I also want more not! Very good product!
