Dear what take another ...

I have me worried for this device model works with Styrodur and must say that it has worked better than me at first, but the rich 4 (FOUR !!!) AA batteries approximately, for a quarter of a square meter, then they are almost red hot and completely sucked empty.
After about 12 hours of work, me the wire from the wire tip is broken. Unfortunately, this is not interchangeable and therefore now completely useless. The archwire is okay, but does not come naturally to the performance of a real Styrocuts zoom ... the soldering iron is (logically) complete crap. If the time has become really hot, the batteries are empty again.

Conclusion: cheap product, cheap processing, short lifetime, high battery consumption ... therefore: The Money Pit.
