The device is not to be used basically as the manufacturing tolerances in are good and evil beyond. The Spempel have a play of about 0.5 mm in vertical as well as horizontal direction, which are not sheared off the edges but somehow just squeezed caused when punching. Accordingly, the SIM then looked. (Usual game with punches should be in the range of max. 0.1 mm!) Moreover, the SIM if it is sitting in the punch is introduced not at the correct site. If you slide the SIM into final position in the punch and then punch would direct the chip was in the bucket, I had to withdraw about 2 millimeters back the SIM from the end position, so it was more of a guessing game and luck that my SIM then also by phone was adopted.
The slot for Nano is evidently not to use because Metallgrat from the production process is still inside and not to get out.
All in all I can say no buy recommendation for the punch.
9 Euro für'n Popo and almost wrecked the SIM. So stay away from this junk!
