Product purchased and received 3 days later (already is top). Then the product itself is of very good quality. I got an old 3310 with a battery that held only one day. She has three days to completely discharge for the first time. Basically for 3 days I had only one battery bar, and I used the phone all weekend. I reloaded before yesterday and the battery is always full. Maybe I am fallen but for me it is a perfect battery. No complaints.
