Cons
Con No funky animations/ No different navigation windows
Most of users like to see some type of funky animation, whenever they tap any setting, it makes them to believe that something is happening. But in this there is no funky animation or something, just straight to the point, tap the setting and save the power that's all. For some users it could be a con.
Con Needs root (by design)
Needs root to update the hosts file.
Con Won't block same domain ads
Because the host file can only redirect domains, if the ad and content are on the same domain the ad will be displayed.
