I have seen a MC21SP "Rothmans" kit from china fitted, it was extremely ugly, non-matching colors, non-matching sticker, wrong sizes and places, and they also added a number 2 to the number plates... it was terrific ... Paint quality and laquer was not so bad, but that replica bodywork was done without paying attention to the details at all.

Also, a good friend bought another china kit, for a NC30, standard colors, the paint was not so bad, correct colors, but it fits quite bad. We have to use the Dremel too much to get them fitted into the bike. Another point, is that they don't care if the paint goes to the inner side of the bodywork, so you can see the paint sprayed all over the inner side here and there.

As watfordhorn says, the quality of the copy kits can vary greatly, the difficulty is how to know what's the good one ...

For my bike, i have restored the originals, and bought originals stickers and paint too, it's harder and it's not cheap, but there's a big diference !
