Short killer ts-30a and hot tweezers Vihua 938D

This device turn on.. its quick in finding short circuits.  I only used it 3 times .the only problem is one of the power pins of the back socket is loose fell out. you just need to solder it in again. i provided a loose pin with this item.  i have turned it on again since the one pin fell out and it still works i just carefully inserted the loose pin in its socker again.  The second option is you can replace the plug with a new one and this will just work fine. i am also selling my hot tweezers with this short finder. the hot tweezers works. they just need finer tweezer points and can be replaced.
