troubleshooting configuration and actual IMU placement is painful, honestly if you want SlimeVR wait for them to actually start shipping a product or prepare yourself for "cheaper" tracking.

Still have errors, still have to tune after the automatic calibration to get close to good tracking unless you figure out a system for solid mounting, pros are the massive battery life due to being able to choose large capacities (mine are ~20hrs run time estimated by the battery sense on the microcontrollers)

TL;DR It's cheaper if your time is free, not as accurate or easy to troubleshoot.
