Chinese manuf. carbon fibre wheels

Been looking at alot of different sites including ebay, I know that alot of these are also the Taiwan wheels.

My question is I was on dhgate.com and seen alot of ffwd and zipp wheels for under $500, Are these just Chinese wheels with decals stuck onto them?
And is it safe to order a set, like has anybody boight of this site before?
And anywhere else I can buy similar wgeels?

A set in particular im looking at are these 808's

Seem decent with the novatec hubs but it says in desc. "After order we need 3-10 days to paint your wheels" so I suppose these are all the same just with different paint.

I dont mind buying chinese but it would be very nice to get branded wheels because they would make my build look brilliant. (Giant Tcr with zipp wheels :-) )
I already have a set of corimas so these would be spare deeper wheels. Thanks
