what's the difference between the 5th generation 3D NLS and other version?

Firstly, the appearance design is different, the 5th generation make it loods more processional

second, software different, the old one is very complicate to install, that's the reason why so many supplier sell 3D NLS with laptop,

The 5th generation 3D NLS much increase this function, colorful backgroup and make those function can be use.
