I went from Viper to MeanRom and never looked back. Even using Viper's CPU Control I still don't get the battery life that I do from Mean. Not to mention Mikey is focused on one sole device and Viperboy's attention is divided by at least two (3D and 4GLTE) maybe more I don't go to all the forums. Also, I use gps a lot my phone (Hardware Ver 2) runs a lot cooler with Mean then Viper when using the gps for hours upon hours. I've even used it for a 14 hour singe day drive once the screen was never off (I did use a car charger of course lol)
If you have a problem or issue with some one PM them keep it out of the forums.
