They’ve been giving their devices away to every electronics YouTuber, you really see them everywhere plus the sponsored ads. I’m not really sure how many hobbyists really need a scope like what they make, though.
The low-end crap is not particularly profitable, but best not to cede to your rivals as long as you can at least break even.
The high-end stuff makes great marketing and probably sells better than 3 per year... though that might just be 4. JPL and Los Alamos don't really need this stuff, though they probably have something somewhere. It's really designed for high-bit-rate stuff. I seem to recall DDR5 lowest-level debug being a major use case for the UXR in the early promo materials. I'd imagine it's also pretty good for some LTE stuff. And phased-array radars, because it seems like that's always what the highest-end stuff is for, no matter what it is.
