The problem: I tested the product and the plastic thread does not fit into the nozzle, after several attempts, I decided to take everything apart and there big disappointment, I find at the loading tube nozzle side an old piece of blue plastic stuck ... I only used the orange wire, so I can only assume that there was a previous use grrr But right after I hard to remove, with paper clips and other needles and tweezers, the pen works (phew!). Fortunately it is easy to disassemble, but it is not without having damaged a little (and worse guarantee level and everything)
Finally last point, the temperature adjustment component (which requires a precision screwdriver), it is unclear in which direction turn to increase / decrease the temperature (when tests and tests) and finally it takes grip (but this is not the most technical)
