Review on Cord Hider for Speaker Wire, Ethernet Cable – 142in PVC Cable Concealer Channel, Paintable Cover – 9X L15.7in W0.48in H0.32in – Beige (CC05) by Aries Boyce

This worked well to hide the ethernet cable on my wife's desk. However, it is not very easy to install. One reason is that the adhesive strips come separate from the actual cable cover and you have to peel off one side of the adhesive, stick onto the cable cover as straight as possible, and then peel off the backing to attach to the wall or whatever. Another thing is that I didn't want any gaps between the parts. They are all about 15 inches long so I had to use 8 of them to take the whole wall off. It is very difficult to align them perfectly to achieve this. and of course no adjustment when hanging on the wall so it works but needs improvement. It took a frustrating hour or so to fix this.
