The imposed by the telecom switching to IP telephony forced me to change my tel cabling - among others needed a patch panel. For this, the purchase of a LSA Anlege- / Auflegewerkzeugs was required. As the scope of work was limited to about 50 x contact hang up, I have resorted to this "low part" - despite the sometimes negative reviews. Have first gearbeit with such part. So: It works properly and even the overhanging "wire" tails were pinched off automatically. Tip: Make sure that the tool accurately + horizontally rests on the contact to be processed so that it does not jam when Rein Press. By the way: The Cases pictured was not present at the delivery and the supplier has not even responded to my "complaint". However, since the product and not the supplier is to be evaluated here, there is a perfect score for the device.
