Well, maybe I did not expect for such a low product too much. The LAN Tester is good and functioning properly. He has already served me well! But that's the only thing on the package, which works well. The pliers are inferior. The cutting function works in a maximum of 50% of the cases, because the knife blade to flex against the cutting edge and thus the cable only bent, but not cut. The Quetschfunktion also ensures not always for the right result and you have to sometimes 2-3 times nachquetschen so that all cables have a connection. The LAN connector have no insertion. The biggest drawback to it is that the plug does not really lock into the LAN jack. Thus it is only loosely in the connector and can slip out again. I would not buy it.
