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 for the ADSL box (ADSL modem + router portion) to protect it from power surges from both the electrical and telephone network but I use the normal version (without the "@ Phone" Eaton (MGE) - 66710 - Multiprise - Protection box 5) 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 wanted to connect an external antenna to the TV decoder (some versions of the HD box with integrated digital tuner).
