I liked using the website. I used Virool to get more views and YouTube subscribers for my music video. I spent $1000 so far and got 20,000 Virool views and about 30,000 views on YouTube as a result + 1243 new YouTube subscribers. The promotion wasn't cheap, but the people seemed real. Scott from their customer support team helped me out through the process and helped me understand the analytics.
Overall, it's a good tool, but requires some tweaking to make it work right!
