We have them at home as well and they really suck. They lose connection every 20ish minutes at best, and take about 5 to reconnect. Makes Zoom meetings impossible, among other things.
It’s worked well!
You do need to be a bit careful as coax signal can be shared with neighbors and others sometimes.
You can buy them online for around $10 and they install without tools,
Besides neighbors, you may also need a POE filter if you have certain types of cable modem.
In general they do suck, but they can be pretty decent if you stick them all on one phase, even better if all on the same breaker.
