There's something there, but I'm not yet sold on the moat.

I've held $SMLR since 2020. I see the recurring revenue contributing to the moat (the more broadly the device and software are in use at the organization the stickier it is). I agree that the customer concentration is certainly a risk. I also like the optionality here—they have 3 other devices in the pipeline.
