It's been working great for me for over 2 weeks now - major snow storm did not affect coverage at all. As a temporary set up, mine is screwed to the picnic table in my side yard with the cable running in a window that is slightly opened (with foam and weatherstripping to plug the cracks). It has just enough of an opening there to get good coverage. When the weather gets nicer, I'll put it up on my roof and do a permanent cable run.
Very happy with the performance so far. I got up before others got on this morning to run a speed test: 201 Mbps down, 27 Mbps up with 35 ms latency. I've done several Zoom conferences over it that have worked well, even with my 2 kids each streaming YouTube at it's highest resolution at the same time.
The Starlink smartphone app has a feature that tells you recent performance statistics. Over the past 12 hours, it's been down for 11 seconds due to "no satellite coverage, and 4 minutes due to "Beta Downtime" (which I gather is planned downtime as they tweak software or make other adjustments). Bot of those numbers will drop as the number of satellites increases and the system matures.
