This cable is technically CAT5e certified, but in general it's one of the worst grades of cable I've ever worked with. The outer PVC jacket is so thin that the cable can be kinked extremely easily when exiting the box. I mean, if you're doing some house wiring, you'll probably be fine. If you're doing commercial work or somewhere that's subject to some degree of wear and tear, spend the extra money and buy the next pack of better quality cables.
