It's good enough for the girls I date

It caught the 7 wire on a bad plug I'd crimped and saved me from going berzerk later. This isn't fancy, but it sure is useful. This is just for use in my home.

This LAN cable tester is a great value

I used it to identify some 'mystery' network connections in my house. This tool worked great and was easy to use. I would have paid 4 times the price.
