I like that we can see in one place where our ads are placed (both horizontally as well as vertically). The interface is very clear and user friendly - so easy to use! And you get excellent support from GT. There's nothing much to dislike about it. It works pretty good for me - but there might be something better out there if they have more features or options. We're using this mainly because of it's ease of use, it's great customer service, and price tag. We've seen how effective it has been at increasing ad revenue and helping us manage our inventory levels by showing exactly what pages sell best.
