Worst "customer support" ever
The products are cheap and working more or less. But the "YI Customer support" is ridiculous. The often answering with standard phrases (reset the cam etc.) but never got something helpful information from the "support" and then setting the ticket to "solved" even nothing was done. For me it looks like that the YI support staff is not educated or understanding English nor there seems to be approbierte education of the products they should support...
