I was happy to see this appear on AppSumo again as it is a well established WordPress plugin. It is similar to other page builders available. I would like to see some more unique interactive blocks compared to other page builders. It has plenty of templates already to use. It is also better than most of the other page builders that have appeared on AppSumo.

The most important part is that they have active development with a changelog.

It is worth a punt for Tier 1 if you have a few websites. Compared to their normal lifetime deal direct from them then it is much cheaper if you do not need unlimited websites.
