Very good impression of solidity and quality at the opening of the box. Perfectly compatible with Freeplugs to interconnect the two housings by CPL Freebox HD / v5. I use the "Tel @" Version (Eaton (MGE) - 66711 - Multiprise - Protection box 5 Tel @) for the ADSL box (modem + router ADSL part) to protect it from power surges from both the grid and phone but I use the normal version for the HD box (decoder part TV) though I should have taken the version Tel @ + TV (Eaton (MGE) - 66934 - Multiprise - Protection box 5 Tel @ / TV) if I had wanted to plug in an external TV antenna on the receiver (some versions of the HD box with integrated digital tuner).
