These guys have set a very high bar for how Appsumo deals should be.
The tool itself is awesome. But what is even more amazing is their team's commitment to quality and constant improvement:

- great support, fast response time, issues get corrected (80% of what makes a good software per my opinion)
- new features and niche templates added on a regular basis
- a genuine interest in delivering quality and meeting their clients' demands

So, long story short, we have a winner. Software makers, take note.
