It's very easy to set up campaigns. I can create an ad copy that will be sent out directly from my referral link without having any code written myself - which is great because it saves time when creating new ads/campaigns quickly. You don't have access until you get at least one sale so this could take some getting used too if they're not converting right away but once someone does convert then all of their future conversions are tracked automatically by them. This makes me feel more confident about sending people over since we know exactly how much money each conversion brings us compared to our previous method where there was no tracking available after initial signup via links only.
