... Review revised after 4 months - minus 4 stars

Text of the second review August 2012:
Overnight, the battery was without power. Not even in the charging cradle a conversation could be accepted. The error first adopted the phone but was due to the battery. After use of the old Siemens Battery everything worked again. As more customers found this catastrophic failure happen overnight, I put the quality of the product in question. I will still be a new exchange - Order Battery. Amazon took the faulty goods back without hesitation. The vendors themselves first demanded that I stamped the battery should submit. Is not at all !! If the new battery function (and not only 4 months), so I'll gladly revise the review for a third time and again awarded more stars! Just take a look ...

Text of the first review March 2012:
It's the big question is how the battery works in one year. Now, after a few weeks, I'm thrilled. Significantly shorter charging time as the original, and he also holds three times as long. It is the purchase price of Siemens Gigaseit SL 78 H outrageous by the manufacturer as the original - Battery "not" work. After 2 years the original is - battery to use only a few hours. Many other reviews I could see the same defect. False economy if that does the brand image of Siemens well, I doubt it. This exchange - battery is working properly. He does not get hot and I have found no other faults. I seem to have found that the voice quality has improved. Perhaps the transmit power is positively influenced? I do not know - is also not been decisive. I speak here from a strong buy recommendation!
