I bought two of these to use in conjunction with the Belkin Surgecube to allow for the protection of my new Belkin ADSL Router from any phone line based surges that might occur.
I can't say much about the cable itself, only that it is bright white in colour, built extremely well and provides a clean fast transmission as expected from any Belkin cable, personally I don't use any other brand name for cables unless I really have to, Belkin really know what they are doing when it comes to cables weather its Ethernet, USB, HDMI, Firewire etc they just ooze quality and if you shop around you can get them a lot cheaper than their retail price.
Speaking of price, the value for money of this product is fantastic having at this time picked them up for £[] each on Amazon, it is an absolute steal and I would expect that somewhere like PC World would be selling the same thing for 50 times the price on here.
Highly recommended product.
