In general a lot of Chinese DIY electronics manufacturers are known to behave this way:
- sometimes they may not apply necessary Q.C. before releasing of a product from factory ;
- they may arbitrary change schematics and electronic components from one batch to the next one ;
- they may terminate manufacturing of a board just few months after initial production.
