+rep We traded one of my high-tier games for 10 of their freebies/low-end games. In the end I got 10 games but not the 10 we agreed upon. Also, it took more than 2 hours to get the trade sorted out. I don't doubt this trader's honesty, integrity or willingness to compensate. But one should be wary of the quality of some of the keys obtained freely.
Edit: to be fair, this trader went out of their way to make sure I did get the 10 games we agreed upon. They contacted me the day following our trade to let me know they had revised my games list and didn't see one of the 10 games. I checked and I had missed one; it was a duplicate code. They sent me another (working) key just to make things square.
All in all I would trade with them again, just not when I'm in a hurry :)
