I have what I suspect to be a Quando (110mm, loose bearing, fixed-free, low flange, black). Costs a whopping $13, brand spankin' new in a shop. That's pretty much as much as it is worth.
I stripped the lockring threads through a combination of poor design (too short threads for both cog and lockring), mediocre manufacturing (threads), probably subpar material, and user error. Other than that, it gets the job done. Now the cog is just rotafixa'd on, but it's working, and the bearings have survived on and off winter commuting with just one repacking done in January. I'm sure they don't spin very smoothly, but then they didn't when the hub was new.
About manufacturing tolerances: one section of the dustcap touches the hub shell once in every turn... Not a very round hub shell, but who cares. Now it has 1500-2000 miles on it, and it's still spinning

Can you post a pic of the hub? Quite possibly it has nothing to do with my POS
