From what I've read it works.
My concern about "one click root" apps has not changed through the years and that is: it will lead some folks into rooting without the necessary knowledge to get out trouble if they encounter issues. If folks read until they thoroughly understand what the rooting process is and decide to use a one-click just to save some typing, ok. But they decide they do not need to understand what's being done to their phone, well that another..... I'm sort of old fashioned and think people should learn how to do all this stuff and follow the guidelines. I don't think folks should even use Rom Manager to install roms, make backups, etc. They should do it manually. But that's just me and I know thousands and thousands of folks are using Rom Manager everyday. So there you go....
Just my opinion and YMMV!!
Good luck.
