D6 headphone Buyer Real Experience and Three Days Feeling

When bought D6 my buddy(cell phone shopkeeper ) went with me and we picked the goods directly from backstage(his purchase shop), European version D6, K3 edition with one original battery and one group battery, cable, Video line, seat charger, direct charger, headset(I tried all and all of parts can be used ), 2380yuan(buddy told me it is delivery price) . I bought another original battery with 100yuan,totally 2480 yuan. And then paid 175yuan to buy 256 TF card with card reader,all of these add up to 2655yuan. Buddy asked me if I still want to buy Bluetooth headset adapter. All of above is enough for me ,and in my mind Bluetooth headset transfer files not as practical as card reader, so I did not buy Bluetooth headset and Bluetooth headset adapter(saving more than 200yuan) (best earbud headphones). The two original batteries are not durable, the first filling after 10 hours, one of them only use for one and ahalf more and the battery is low for tips, may be I play too hard? Buddy told me refill them after use up,repeat 3 times, if still so he will take me there to change...... If not believe buddy I won't buy two original batteries, it can also save 100yuan to buy commercial battery.(Tips: when buy D6 pay more attention on battery.Buddy told me purchase price of group battery only 5yuan. If business use group one to pretend original one, you can see how much he earns from battery?)
