I recentley ordered the 24 seasons 1-7 thinking that i was getting the original released box set, as your probably aware from other comments from this site i didn't get that, i got 1 box with 24 printed on the side with the dvd's stacked inside in plastic envelopes.
I am positive the are pirated copies but it seems the chinese can do whatever they please because this site has been running for a very long time.
The dvd quality was ok though and as long as you aren't bothered about buying original dvd's then go ahead, but after reading other comments about the problems they've had getting there money back and getting rubbish quality dvd's i will not be using them again and i would recomend you don't either.
