Works fine but only after you fix it. Mine had an SMD capacitor that was barely hanging off one side and when I touched it a part fell off. Just by luck I found it on the ground. Another SMD cover was soldered on one side only. I checked all SMD components and made sure they are soldered correctly to the board. The screen barely held up and was poorly attached to the circuit board. I fixed it too. So think of it more as a kit to test your SMD troubleshooting and repair skills. After everything is assembled, it works perfectly and does what it is supposed to. It's accurate enough for everything I've tested it on. Please note that it is different from the two most popular versions of this device, so any cases you find on popular 3D printing sites will not fit without modification.
