Review on Universal Keystone Punch Down Tool For Cat6, Cat5E, RJ11 And RJ12 Jacks By IMBAPrice by Todd Taniguchi

I first tried to build keystones by holding them in my palm, it creates quite a balancing act holding them as you coordinate the wires into the correct slot while using the punch down tool. Not too mention the possibility of punching down on your palm and cutting yourself. This tool helped a great deal by holding the keystones in their place, protecting my palm and increasing my productivity tremendously. It comes with three compartments (A,B,C) which confused me at first, since there was no instruction manual that came with the product. Apparently in US markets only the B compartment is used as its the standard for US keystone size. Otherwise, the tool is good quality, and I would recommend it if you have to punch down more then one keystone.
