I have one and it's really great. Went from high latency 10mbps (calnet) to low latency 150mbps (starlink). Prior to calnet we had geostationary satellite which was unusably bad and would try to tether through Verizon but signal was very weak.
It's life changing if you're in an area without other options (though it does suck it's taking a long time for people to get access).
I bought it for my in-laws in Placerville California for when I’m there so can’t easily check right now, but I recall 24-40ms typically closer to 24-30ms.
Probably good enough, biggest pain is finding a view without obstructions from trees.
