This is a quality tool that does a great job of securing Ethernet cables and other types. Damage, except for a few small scratches on the metal surface. It requires quite a bit of grip strength to activate. So if you are a woman or an old man (like me), you may have trouble using it in awkward situations. I would recommend using 1/4" to 5/16" terminals for Cat6 and Cat7 cables instead of 5/16" to 5/16" terminals unless you want the cable to be slides easily through the main product.
