Here in Colorado my service is actually pretty good - I get 20-30mbit during crowded times, and 150-200mbit during off hours. Outages were problematic a few months ago but have improved and now usually coincide only with severe thunderstorms.
Overall, it's a literal order of magnitude better than end-of-line ADSL and roughly a 2x gain over my old WISP (at 2x the cost). For someone who used to have access to a WISP, it's evolutionary. For locations with no previous access at all, it's revolutionary.
On the flip side, the hardware is almost offensively silly and ridiculous (proprietary connectors and cables, router with 0 Ethernet ports but a diagram of Mars instead, etc.). IPv6 support disappeared sometime last year, and everything is behind a CGNAT. And link quality sometimes seems to depend on the dish repositioning algorithm picking the correct inclination, which seems to be a crapshoot depending on when it was last rebooted rather than an ongoing correction process.
