R-Box PRO box?

Hallo.

I am looking for an Android Box for Kodi.
I have been looking at R-BOX PRO and it seem’s to be very sweet.
I will run my content from my NAS, all wired with LAN.
Will the R-BOX PRO be able to run KODI and the movies without lagging or just run slow..
I want a fast and non lagging interface.

Thanks for the help.
