Freestar allows you to take advantage of all the tools offered by Ad Exchange without having to worry about creating a campaign or writing code. Their customer support team is also top notch. It would be helpful if there were more reporting options available (e.g. I would like to see click through rate). There are some limitations with the API that can prevent you from using certain types of campaigns/ads. However it's not bad enough to make me turn away from this platform overall. If you want to use an industry standard SDK and have access to our massive network of inventory, then there really isn't much for you to lose. This is an ideal, plug and play solution for advertisers who just want to get results. The platform is very user friendly. It's easy to set up campaigns, track performance and target users. There are some minor bugs here and there but nothing that's noticeable or even annoying. I'd recommend giving it a try! We've been able to improve our ROI by 10x with this tool. We were using other platforms before this which were not as effective at tracking our conversions.
