It has all the downsides you'd expect from an IMU method with so few trackers for the legs. Feet glued to the floor, floating hips, hips bending the wrong way, struggling with slow movements, drifting faster if you're not standing etc. Recalibration is also the same 15-30 minutes you see on other IMU methods. Using a phone to recalibrate sounds like it could get annoying while in VR.
