AngularJS framework, AngularJS DataGrid

I need your opinions as web developers about the framework I built in the last two years:
Presentation site
, comparing with existing framework: Material, Kendo-UI, etc.
This contain a complex Data grid, with some features I don’t seen at other javascript dataGrid’s.
I tried to create something real simple to understand and implement, and very flexible.You’ll decide if I succeeded :).
At pages bellow Show case menu option, you’ll see real life examples.
