The best way is to ask for pics from the fron, back and CD matrix. Otherwise you can’t be 100% sure.
I have an original! I compared the cd with my friend 'and everything fits, even the matrix!
now I’m happy to have a HTep. now I have almost all the lpu cds, lpu2.0 is still missing! go to search 
It’s quite sad that there are so many HTEP fakes sold on eBay. With that large sale five years ago, you would have expected something better. Especially since many people ordered like 10 copies so they could resell them later.
