Just want to chime in to say how good the Shuffle.dev team is! I had a billing issue where I was locked out of my account due to an issue with PayPal's webhooks. Dawid (the Founder) responded very courteously to my strongly-worded email, and worked with me to fix the issue.

A really great guy, and a great product! I mostly use the Tailwind builder, the top comment on the ProductHunt page is mine and has a bit more detail on the story: https://www.producthunt.com/posts/tailwind-builder-2-0.
