I really like the idea of the keystone jack rather than perforating the entire panel. This way you can create all the cables on your desktop and just plug them into the panel (provided you don't pull the cables out of the wall, of course). You have very good control over the work area where you punch the cable - a big plus. Once you get the hang of it, hooking up keystones to a patch panel isn't difficult either (I'll need time to figure out the best/quickest way to do this). For a beginner like me, a quick drawing showing how to attach the wire would be nice too, but Google was my friend. The only problem I encountered is the cable marking. The TIA568B colors do not match on the green-brown side. I had to swap green/brown to match the RJ45 connectors. The professional cable builders certainly don't care, because they can lay cables in their sleep. After a few initial failed attempts I got the order right and the label didn't matter. I mention this to advise others. Please note that although I am color blind, non color blind family members have confirmed that the colors on the label were indeed wrong. My advice: try it first, test it and see what happens where if you succeed. Then rinse and repeat. I would suggest that future labels include the NAME of the color as well - I understand printers can pick bad hues, but a little text with the intended color will clear up any confusion. All in all - I would buy it again at any time.
