I have wired most of my house with new phone and ethernet cabling. This set performs fine. No surprises. The punch down tool is a must-have for terminating into Leviton Quickports (as it punches down and trims the wire simultaneously). There are more professional tools out there, but this set has been great for do-it-yourself networking. And I don't think the network is any worse for it; everything is running at gigabit/second. Amazon's $40 price is good.
