UWB PK-1000 Standard Edition

Weird that MD didn't put SEEED in the title, as they do for many (most?) other items that come from there. This looks fun, but not $700 fun, at least not for me. From the comments section, you can track multiple objects at once, however the tags aren't sold separately, so you'll be spending $700 per object.
