@alex11, thanks for your kind words. It is the best gift to us. 
@TokyoDriftPSP, thanks. We definitily don’t make loss. Don’t worry. Donate is a good idea, but not feasible I am afraid. If we do so, our finance would complain of getting a lot of unidentified money. 
We are expanding our capability to provide more valuable and affordable service to the community, like the turn-key manufacturing service, Acrylic service, prototype service and ect.
