Positive aspect is the choice of 10 colors Hard Wax pins. The smelter is a cheap processed plastic part. Instead of a real switch for turning on / off of the unit, there is a stiff contact which heats the device only as long as long as it remains active pressed. Until the smelter reached operating temperature is one of the fingers fall asleep, which makes an accurate work. The unit also had only screwed before operation and a wire soldered. This is certainly not in any device necessary, but their design probably happen more often.
My Recommendation: In Bauhaus crayons buy á ca. 3.-, to melt a hot glue gun, which is operated at idle, optimally for about 4.-. Colour for Several wax crayons can be well mixed with the glue gun, the battery-powered smelter produced it in my case, too little heat.
