got my trackir 5 the other day. it came by ups.
i ordered the pro clip, and they sent both the pro clip, and the little metal thingie that goes on a hat.
i think they've modified the pro clip, as mine had to be partially assembled when i took it out of the package. the part that sticks down out of the clip itself is on a pivot now. it just snaps in. the part some of you mentioned as a weak point also is a pivot now too.
the extra wire thing was going to be a bit of a problem. i temporarily solved that with bread ties. tomorrow i'll bring home some vacuum hose, and place both wires together in this. i tried it on the headset, and can't even feel it there.
the camera thing that mounts on the monitor is smaller than i expected. i don't much like the base, as it angles the camera down, and the base legs do not adjust enough to securly fasten it to my monitor(acer C223W). i will be fixing this also with vacuum tubing.
im too tire to download and install the software tonight, so tomorrow night i'll do that, and update this. i'll also bring my old digital camera home and snap a picture of what i was talking about with the pivot points on the pro clip.
