Several owners here have used them, but they are definitely on the cheap end. Comparable to Godspeed, Ksport, etc. Sh*t valving and not very many damping adjustment levels, but you get what you pay for.
For daily street driving, they aren't terrible. But Fortune Auto or even BC's will perform better. Certain models such as the E12 Note even have Ohlins coilovers as an available option. Check Yahoo auctions JP, Crooober, Buyee, etc. Look around and become familiar with all your options before you buy.
