I have been using it for about a month on blogger for 4 blogs. .50 cents a day, I have been doing better building links using their link building tool for a few Squidoo lenses.
If you build links, you want to be mindful and check Viglink's list of partners, because partners are dropping off all the time, and with some like Walmart, you have to get special permission from Walmart. That fact was not clear to me at first.
I tend to use Amazon and eBay links so I don't worry about a drop out, would be a hassle fixing drop out partner links all the time. Viglinks will not notify you either.
These links are paying per click.
