Looking at the metrics incorrectly
The snapshot of a single point in time is misleading. The trend is what is most encouraging, or discouraging as the case may be.
Revenues were increasing through the 2010's, peaking in Q2 2016. It was a long decline from there to the bottom in Q2 2020 ($33,864). That decline is obviously disappointing. No base of consumers had been established. I'll grant you that the company made some big mistakes that didn't help. i.e. the CE mark. Going NHS rather than OTC in the UK etc. But it remains that there was not enough consumer interest to maintain sales. After all $ 33K globally for a quarter is pretty shabby.
With the onset of the OEM model, and KT coming onboard, we saw a return to increasing revenues. Unfortunately, that only lasted for ~3 quarters. Again, we see declining sales. This is a clear indicator that consumers are not adopting the product. Word of mouth and return purchases should at least keep us steady (and more than 50 - 100K a quarter).
So, it's the trend that matters here, not any one snapshot in time. Yes, the last quarter was higher than the previous two. Is that a trend.? Not unless the increases continue for a couple more quarters. Twenty years hasn't been enough to build a consumer base, but maybe a few more quarters will do the trick.
