The stripping has also simultaneously a Abschneidfunktion which is quite handy. Can with a screw to adjust the be stripped wire size, unfortunately this screw for my cable (Cat.7 Verlegekabel, 4x2xAWG23) was a bit too short, but with a bit of tact you get that too without the screw back - once turned carefully around the cable and you can remove the jacket.
The cable tester is testing in two different speeds, he tests all 8 contacts and the shield continuity, since the latter a great importance is the functionality in my opinion completely. A test for the possible speed that can be erziehlen to the cable under test would be nice, but you can not expect in the price range.
The crimping tool I have with EFB Cat.5e plugs (shielded course - the go easy to 1000Base-T Ethernet) test, which is absolutely no problem can be crimped, once pushed to the end, the wires are contacted clean.
So all in all I am absolutely satisfied for the money spent, I expected much less functionality and rickety tool, but here was very pleasantly surprised.
