they're a gem if you can work with a trailing cat 5 cable plugged into one.
If you're doing trailing CAT5 cables, then why not do the right thing in the first place and install CAT5 throughout.
Power cables were never meant to transmit data. Performance and reliability will always be better on CAT or Fibre.
Powerline adapters are nothing but a cheap gimmick to keep the lazy happy !
