Suitable for tying a notebook. The fuse is mounted quickly and gives me the opportunity to sometimes on a construction site, the notebook for several minutes unattended. A real challenge I had in an office setting where the notebook on a table in the middle of the room without crossbars. The connection to a table leg was not useful, because each steel cable including notebook on the table leg used could have moved. My solution: I have drawn the cable at the same time to a table leg and a free office chair. It could thus not be solved without the appropriate tools and without a key.
Bit fiddly is the insertion into a device to be protected. With a small return spring, before locking automatically adjusts the rotary lock in the Freigabepositon, it would have been worth my 5 points.
