Review on trueCABLE 1000ft Black Cat6 Shielded Riser (CMR) Bulk Ethernet Cable - 23AWG Solid Bare Copper, 550MHz, ETL Listed, Overall Foil Shield (FTP) by William Lara

This material is expensive for a reason. It's thick and really well made. It's significantly thicker than any CAT5E or CaT6 I've bought from a big store because the shell is thicker and the chamber is thicker. This also makes it less flexible, which is not necessarily a bad thing. The build quality of the box is also nice. All round high quality product.
