I have a G2 VR, Tobii, and TrackIr. Tobi works pretty well once you set it up properly and you don’t need to wear anything for it to work. Which is a big plus to me.. neither track nor tobii compare to VR at all.
I work from home, so it’s nice using Tobii playing DCS while working. I can still see my other screens with my work apps, while not having to wear something on my head all day like trackIR or VR.
Cheers,
