The main way it differs is in that it's fake. You will not fine anything legit bought online in China. End of story. Back when I used H3 Neo Prov, I only bought from provincial players or authorized DHS dealers. Multiple sources (former provincial team members) said that these sites will look super professional and legit, but the equipment is as legit as a 10$ national sheet on taobo.
Spare the appeal to authority fallacies. I myself have dealt with Prott as have many other members on this site with no issues.
