Initially I was sceptical about this company providing game keys for very low prices, but since we're talking about a few Euro's here I figured I'd just take the risk.
I was hardly surprised when the key I got was already used. I figured this was just another scam company, but decided to fill out a ticket and contact support anyway.
To my surprise, the live support chat was both quick and extremely helpful. I got a new key in minutes that worked. The support person even waited for me to get the new key and activate it to make 100% sure the new key did actually work.
All in all, I'm a happy customer that would certainly recommend this company.
