The Tundra dongle is legit sketchy, word has it that they're discontinuing anything but the 3x one.

Never had any trouble pairing or connecting mine, just very unstable just after turning on, and tracking constantly resetting as if it can't see one of my basestations. 

My one Vive 3.0 hip tracker is rock solid.

Early Kickstarter units though, so hopefully legit faulty and the replacements will do better.

Tundra Labs support is super slow, but they will get back to you eventually.

UnboundVR should reply within a day or two, but their emails have a nasty habit of... never arriving, so contact them again if it's been more than a few days.
