Simple tester at reasonable price
Nice build quality. Very quick to test, gives a clear pass or fail… however it doesn’t give any real information about which line or where in a cable (distance) the fault occurs… however Klein does make devices that can do this at a premium. Sturdy and dependable to test cables prior to deployment though in the field.

Basic Expensive For The Quality
expensive for an extremely basic tester. limited to only certain ethernet cables. not recommended. this brand has reinforced the fact price doesn't necessitate quality.
