this plugin doesnt even deserve any review, i think appsumo is the best market around and they should check out everything before they accept the deals here,
also the developers should test everything very good before they publish on the best web app market (appsumo)

1- the plugin is working without any serial key. which means its the same if you buy it or not its still working. but the big problem that this is not the main problem.
2- to active the plugin you must active another plugin which looks strange.
3- every thing in elements are full with bug and not working and i contacted the support and they said they are still working on that.
4- it will destroy and damage your wordpress speed. even if you still didnt use any element. just activating the plugin..
