They appear to be good quality for the money. I haven't used them yet, but they seem to be well built.

The tester works perfectly. The master even works if the other end is plugged into a router. The crimping tool is also good, but it doesn't have a blade which comes down while crimping. Most others don't have it either, but if it did, it would make crimping pass-through connectors much easier.

Felt a little cheap so returned.

excellent product

Great to have around the house if your into tech and stuff!
