After many ambivalent about recessions Used Iphone battery with several charging cycles I decided on spec for this product. Lo and behold, it is actually a genuine Apple product and fits properly. The APN was identical to my previous battery. After installation I checked the charge cycles over iBackupBoot and it was actually never before put into use. With the right tools and a good tutorial Input & Construction is a child game. In addition, it is outstanding value for money. I'm very satisfied!
