I have FBT using an old phone connected as a camera and some cardboard with QR tags printed on them. Works damn near flawlessly vs the built-in inside-out-tracking on the Q3. Now if I can just get a small little pen camera inside the headset to use eye tracking software I'd be set... 😅

Oh it works great for me. In fact a lot better than the Rift did with its dedicated trackers.

It's also handy to just pop it on and not have to set it up. I often bring it to the office and I've given a demo for friends, it's much harder with lighthouses.

And the cost of them is just insane. If they were 100 bucks for a couple it's fine.
