H12 ads?

I received an email from this network (H12 ads or h12-media) asking me to join. This was a bit surprising as networks don't usually email sites to join them in my experience but I am wondering if anyone tried them. The reviews I saw were not impressive when I googled them but they appeared to be paying.
Also they have some on-video banners that appear to be interesting I would also be curious in hearing some feedback on that (How it looks and how it pays)

never heard about them..

I found this on the first page of G!
