I like that it allows me to put my own ads in place of other ads. Sometimes you can't really change them or it's not as helpful as you would like, but overall I am satisfied with the product, and will continue using it. I have not found anything I dislike about the service at this time. If you are interested in getting more customers with minimal investment then this may be something worth looking into. I am trying to get more business from website visitors by adding a small ad right before they reach the checkout page.
