Useful tool for Micro Sim

I have an effective tool sought, which is a Micro Sim punches me in a nano-Sim and I bought this Sanzer. As the device only works with normal Sim, I had to use the supplied template to punch. The stamping itself went very well. You just have to make sure that the complete contacts are not mitgestanzt. For this you have only the device with inserted Sim look from below, one sees virtually "earnings" already before punching. And with adapter even fits the Nano punched in my iPhone. 4

For me the device was helpful and cheaper than to buy a new SIM card.
