This seller is one of the best sellers on AliExpress. The original shipment arrived at my place broken, but not because of the packaging, but because the post office literally broke it. I contacted the seller and they kindly offered to me to send me another unit. Not even 2 weeks later I held a perfectly fine unit in my hands. The battery doesn't need any further explanations: Once you go big, you never go back. Brought my N7000 back to life. Wasn't my first monster battery for a smartphone.
