Love this platform! I simply create campaigns, set my target and start buying traffic directly after a quick moderation. The navigation is super easy, allowing me to make changes whenever I need to. I like their reports, they organize my stats by different parameters, making it simple to see what's working best. I've even tried making a flat deal and already prolonged it twice. 
Plus, their support team is super friendly, they helped me a lot when I first got started.

Overall, a solid 9 out of 10!
