## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Does the job, but check colour
  

*by C***P on Reviewed in the United Kingdom on 22 June 2022*

No problems at all. Not sure if it's the cable or our router stabilising since the service install in March, but we're getting over 80Mb/s with our FTTC service.Just keep in mind that it's quite a blueish shade of white so might not match or blend with surroundings completely.

    Does not fit a BT socket !!!!
  

*by A***R on Reviewed in the United Kingdom on 31 January 2021*

Bought this to move a router. Read the reviews. This does not fit into a BT socket!!!!!!  It arrived damaged anyway so only 4 stars
