Function insofar OK. Even the wireless work is very handy when time is not an outlet or extension cord near. Drawback: the small drip catch on the frame helps relatively little. If you have screwed the long point, the adhesive runs namely next! Also, I've now found that the glue the back swells when the glue gun ~ not used for 10 minutes. Reason: The heating element does not switch off and thus the cartridge melts gradually up to the back!
