I have just purchased an HI12 and also an H1 pen. Dissapointingly I cannot get the pen to work for more than 10 secs. If I remove and reset the pen battery - again the pen works for about 10 secs and then fails (does nothing).
I have read on these forums that the H1 pen is only compatible with certain H12s I really hope this is not the case as the pen was a main reason to buy an H12.
My serial number is DT2016010197 and part#64G45170402710 is this version of Hi12 compatable with any pen.
maybe the pen has quality problem, you can contact their customer service: service@chuwi.com , and ask them to send you a new one and try it again, have a good day

Thanks for the response but you didn't actually answer my question. I provided the serial numbers for my device to see if it is compatible before I start looking at the exchange route.
