It works well. Actually isn't a scam.
I got a year subscription 59% off. It's fairly noticeable to someone who has semi crap internet. It seems like it works well and is not a scam, despite the fact that it's not refundable. I found that it can very rarely crash your game on loading screens, might depend what game you're playing. This only occurred thrice over 8 hours of gameplay, and I haven't had this problem before. If you're living in a crap area and pay a lot for internet, this will be an amazing product if you can get it discounted.
