It's life changing if you have crappy internet or no internet. It made working remotely much cheaper, easier & better for me.
It was patchy & used to have short drop outs when I first got it like 3 years ago. As Elon put up more space junk the dropouts seem to have disappeared or become unnoticeable. A clear view of the skies is necessary - I stuck mine on the end of a 6m steel pipe to get it. That may not be necessary anymore.
I've not hit any limits & we hit it pretty hard some months. I'm paying for the 'performance' plan though.
It has gotten slow occasionally but power cycling the router seems to fix it.
