that's a fbt puck
when i say outdated i mean it's first gen kind of, index is 1.5 gen but still it has improvement to some stuff
there aren't really that revolutionary next gen headsets out yet that aren't ridiculously overpriced and that have features not supported by most or any game
htc vive should be fine for a while at least unless you want the best of the best, for a budget setup it is very ideal since you don't have to buy separate lighthouses to upgrade it for fbt with the tracker pucks
it being outdated just means it isn't the #currentgen anymore which is just a good thing for the price tag
