Long time customer of AppSumo.

This was the worst purchase ever. Not only because of the tool, which had a few merits (thanks to the developer), hence the two-star rating.

Main frustrations were:

1. Poor usability and poor results.
2. Customer support style and philosophy. It's subjective, but this is how ratings function.
3. The way one-star ratings disappeared.

(This, and the many duds I purchased from AppSumo in the last years, made me more cautious.)

AppSumo was founded on the idea of giving good software at unbeatable prices for those willing to do the testing work for the SaaS owners. I am not sure that this applies anymore.

I might buy other deals from AppSumo, but I will pay attention to how sellers respond to the public. I won't buy anything from anyone who talks like the guy who brought us this wonderful deal.
