Ok you left out that part. 0.13 kg is too light. Works out to 130 grams. tablet is going to be over 300 grams and packaging could add another 150+ if they include box.As for what happened, it's pretty obvious that Hotmid sent me the wrong item since the package they sent has a)a label they printed for DHL with a weight of .13 kg of which I'm fairly certain the tablet weighs far more than that andthe invoice they sent was not correct ($70 "sample mid")
That invoice also seems weird. Not sure what to make of $70 sample MID. Sounds like desciption for one of those lower end WM8650 tablets.
Likely some type of mixup and that other guy may have got your tablet and you his battery. Since HOTMID's fault; they should fix this mistake for you but may ship with regular post to avoid paying courier which means long time to get that tablet. 4 to 5 weeks by standard mail.
