Review on Device for manicure and pedicure Nail Drill DM-202, 45000 rpm, 1 pc., pink by Barbara Obertynska ( ᠌

I ordered it, read the reviews, thought that if it doesn’t work for some people, they can carry me through. It didn’t blow) I thought to go to take it, but I decided to figure out what the problem was. I rang the contacts - there is no power to the pen itself. The problem is somewhere in the block. I opened it and saw that the positive contact was soldered, and the minus one just dangled. I soldered it to the extreme contact, everything worked. Trite bad soldering (see photo). For the inexperienced, a warning - DO ALL WORK WITH THE PLUG DISCONNECTED FROM THE POWER, THE CURRENT CAN HIT
