Is it worth to buy a Runn smart treadmill sensor NPE Run for physiologists?

The NPE Run seems to be constructed, as if it is based on fellnrs treadmill calibration:

copied from there, not declared, and made a 100 USD product out of it? And then, Ray tests it for fun and in his spare time over the weekend with no numerical and statistical data:

So we have a new ANT+ and BLE NPE Run product which Ray can test and can be sold. But we personally would prefer the same setup published as an open source hardware and software platform which can be used for physiology as an open source platform.
