this is a really cool soldering kit that in the end becomes a really useful tool. Usually called transistor Tester but capable of testing pretty much any device that has a maximum of 3 Pins.Things like Resistors, Diodes, capacitors, LED's, Inductors, Transistors Mosfets and what not can be tested. I highly recommend to any one that does electronics as a hobby to get one of these since you canTest all your components now super easily before assembling.
