I wouldn't of known about this site if it weren't for the posts on their subreddit. I have to admit the impression wasn't pleasant because there were several "scammed" posts but I feel like they were isolated cases. And true enough I never had issues with my order, so I guess it really varies from person to person. Besides, I also think that if you buy and use these sites, you take it with a grain of salt since it's a gray market. Other than that, your best bet would be to pick trusted sellers. I did that and found someone level 4 and had upwards of 500+ positive feedback and that shows really nicely with the quality of the order.
