The Good:

-Great looking creatives
-Excellent dashboard and reporting

The Bad:

-Your earnings will come in slowmotion.

I've run them for the last 6 days with ADSDAQ serving first, then Smowtion. Adsdaq was able to give me $45-$50 on each day with just 50% fill rate. So Smowtion got half of my impressions.

Even with a supposed 80% revenue share, I've only been able to scrap between $1-$5 per day with these guys. (0.20 CPM)

*EDIT* - I forgot to mention I used OpenX to...
