Cannot fault the service
Bought 2 pairs of Hercules pass through Homeplugs in July 2012. 1 pair became faulty and Box exchanged them in August. They become faulty again this week and Box offered to exchange them for a different brand after I explained that they literally exploded and gave off smoke when they failed. I did not trust them in the house with a wife and 2 young children. They agreed to exchange all 4 (both pairs) for a set of Zyxel. Very good manner on the phone and I am extremely satisfied with the outcome. My only minor criticism is that I had to try twice and wait a bit longer than ideal before the phone was answered. Overall I would use Box.co.uk again.
