Query: Worked great

I purchased this product for my Gen 5 ipod A3116. It comes with an instruction book let though i would recommend watching battery replacement video available other sites. Removing old battery was tough as they glued it well. Once old one was removed fixing new one was piece of cake. The battery worked as expected. Would recommended this product. However longevity of the item can be judge over time.
