Hello Mate,
YES!! This software is very reliable and safe to use if you want to use it out of the box i.e. use a predefined profile. If you want to tinker around with the software and create your own profile... I'd suggest that you do your homework/research first and then do it.
Btw... I have a JY myself and have been using NBFC since over a year now, it does what it advertises. 🙂
