He is from Taiwan. The guy is true inventor. A ph in mechanics and robotics I believe.You just have to read this thread it’s back about two or three pages
I put what David Chen sent me to to replace yearly and every six months the parts and the part numbers
Worst comes to worse just email him he usually gets back to within a day (different time zones he’s from Vietnam I think) he will even mail you all the parts except stuff with liquid as you can’t send them international
I think his problem is he explain too much what his device doing that I think some vendors steal his ideas ha ha.
But seriously the guy is absolute genius and very humble.
