Query: Fair to worse

Fair wood burner... the burner has to cool down completely prior to changing the tips... or the threads will get messed up... these modern wood burning tools are basically throw away items... not worth the money spent on them. They need to make a latch type of connector or something else... so the threads don't get messed up... and we don't have to waste so much time waiting for everything to cool down between changing each tip... ridiculous.
