Quiet a mix reaction. You are lucky to have good units,whereas about 60-70 percent consumers have horrible problems with T902 pen system,including me. I don't think I should get banned because I spoke the truth.You would rather misguide others to buy T902 with such cheap quality pen system.and then they will come and cry because they brought T902. They are now refusing me to refund me full money. They have not returned the Import duty for T902 which is 20,000 INR.This policy is too bad. Plus they say that since I am not returning the packaging box which I threw in Dust bin,hence they will not return 5000 INR. As if money grows on trees. And the whole time eating process is 6-8 months. Delivery after order:Around 3 months. Return of money:2.6 to 3 months after returning the units. Wasting of time trying to callibrate:Around 1 month. Productive use :0.2 days,not sketching. Wipro Service guys qualification: 0 Drawing produced on T902 :0 Drawing idea creation on Cintiq 13HD:0.2 units(Live demo) No. of installed original licenses consumed in T902:2 One MS Office 2010 And one MS Office 2013. I was knowing about the pen Callibration issue when I had installed these licenses on T902.I foolishly thought that after trying to callibrate about 15 times a day for about one or two months,I will be able to Callibrate the digitiser. Does anyone know how to transfer licensce from one system to another?
