VR SUCKS... or does it???

Does anyone have experience with Slime VR trackers?

Their precision is not that great compared to more expensive solutions from big brand companies. But it’s not entirely clear to me if that means it will constantly be up to 10 cm off (which is kind of a lot) or if it will just gradually lose precision over time since it has no base station to auto calibrate against. If the latter and it’s just a matter of recalibrating every few hours, that doesn’t seem too big a deal in comparison to the savings in cost (and supporting a small supplier offering an open source and open hardware solution).
