I had one of these in the days

it was frekin fantastic. The best was US Navy Fighters and Doom.
You could sit in your cockpit on the carrier deck and look around the place in
your chair before you took off. Awesome.
Would hook up friends with Doom and when they were running around, they would
hear the enemies running towards them. They always shout loud because the ear
phones sealed out so much of the sound.
HUGE DRAWBACK is that no one would ever write the drivers for the program that
were coming out. VFX-1 began begging people to write the drivers for the new
games. New game developers were responsive to include the drivers in their game
if VFX supplied it to them. Better resolutions started coming out and more
complex games. If you have no freakin drivers to have it work in the game then
all you end up having is a pair of LCDs in front of your eyes but the motion
tracking didn't work.
Great concept, not enough brains behind it to keep it going. They even had a
version that was 3DFX when the Diamond 3DFX cards started coming out.
Made you dizzy though if you were flying a plane, turning the plane in any
direction while sitting in your perfectly level and not moving computer chair
while looking in another direction. Body keeps telling you that you are not
moving but everything wrapped around your head was telling you different. Glad
I was able to experience it.
