Total junk and ill-fitting based on SupraSabre's experience.
I just cruised the website out of curiosity. It did not make me confident.
Ali Express is a consolidator, in much the same way that Amazon or eBay are storefronts and conduits for numerous other vendors.
Their "Full Refund" guarantee applies only if you do not receive your order. Beyond that it appears to be largely "Buyer Beware". Items MAY (as in "might", not as in "are permitted to be") be returned for a full or partial refund, PROVIDED they are in unopened packaging.
By the time you figure out the fairings don't fit your ride, it's too late.
The color scheme shown was interesting, but reminded me of a Chinese dragon motif. Would be an interesting theme to develop, but not one I'd want to live with day in and day out.
All of this is just opinion; I've never dealt with this outfit. They might be the greatest service-oriented retailer on the planet for all I know, but it doesn't come across in the website.
