In case it's of interest, I have been using four TP-Link AV1300 powerline units for a number of years now. I'm very happy with them - low lag, good throughput, and they tie all of the various bits of kit spread around my house together quite nicely. I can reliably stream decent quality video to several TVs at the same time using them.
Contemplating getting another, to more some more stuff off WiFi that doesn't need to be using it (i.e., my wife's office, given the amount of working from home we are doing).
