hi, guy, I am not sure it is a good unit. That site seems a new one, not reliable. If you really want to buy a Chinese head unit. I recommend you to get it from Qualir, I have been to that company before. It is a trustworthy company.
I think if you really like the products there , you can have a try , if I were you ,only for the low price I will try . And I have gone there to look the product you said , It looks good . you can try . If it is really good enough ,please tell me !
