Theres a new Tundra tracker Kickstarter update https://www.kickstarter.com/projects/tundralabs/tundra-tracker/posts/3294658

Some of the early test units already shipped within China because they don't need regulatory approval. Here's a video of a dancer using them https://www.bilibili.com/video/BV1BQ4y1a7v3?share_source=copy_web
All looking good!
