Recently I had another issue and my current network is on a 8-port router with a 5 port switch. The internet was slowing terribly and swapping out 50 foot long cables was not practical. I bought this tool and will never go backwards again! All my cables tested fine. My router had taken a dump...Our local Lowe's had a tester that looks exactly like this Extech and they had it priced at $59. Needless to say this Extech was a lot cheaper and even had free shipping!This is not my first Extech purchase so my previous experience definitley help me make the choice of what label to buy. I was not wrong. You can't go wrong with the price and features of this tester! Buy one, you'll be glad you did. ### ⭐⭐⭐⭐⭐ Never quess again *by C***L on Reviewed in the United States on February 15, 2013* I'm pretty experienced at making cables, but some times, when you look at the colors, they look good, but they aren't correct. For years I just relied on my abilities, but now I rely on a network cable tester. It works as advertized, and I would recommend it for anyone that makes their share of cables. ### ⭐⭐ There's better out there *by P***P on Reviewed in the United States on December 8, 2013* I don't care for the slow pace of the test, it routes through each pair one by one as you wait for it. The switch is a hinderance as well, especially for those with failed memories. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/9457501-extech-ct100-network-cable-tester](https://www.desertcart.at/products/9457501-extech-ct100-network-cable-tester) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-25*
