When using the punch the Stifterkzeug is apparently only used for nano-bay. I put the punched on Micro card into the second slot, it can be stamped on the Nano. Here I got it without the pen tool not out again; with its aid, there were also no problems.
Importantly: Do not place in both shafts simultaneously a card for punching a! You can always use only one slot at the same time. A corresponding Waarnhinweis I have applied to the scanned artwork from the packaging back. To be able to read the instructions well, you have to enlarge this chart, in the selected 400% is easily recognizable ales.
If you want to punch from Mini to Nano, you must first punch from Mini to Micro and the resulting micro card then Nano.
Since I do not have devices that use nano, I have now not even tried.
I therefore forgive only 3 stars because the test performed only a snapshot is a rapid test after receiving the goods and can in no way reflect the quality of all product features. Around the unit to evaluate with 5 stars, it would only make its suitability for everyday operation in several missions. This will hopefully be the case.
