I bought Cheerio, couldn't figure out some of what I needed and just got irritated and refunded it. Not their fault, I was having a rough day and just didn't give it a chance and didn't ask their support. I got an email from the founder a few hours later asking me for feedback. I explained my issues. Within an hour I had an email with a video walkthrough of the features I was looking for, along with a promise to implement any missing features related to my use case. I re-purchased it immediately, and am really happy I did. Five Tacos for you, Cheerio!
