This is a very good product. I primarily bought it for its ability to measure inductors and the ESR of capacitors. Multimeters with these capabilities are rare and not cheap. I have experienced one minor issue with this device but with some attention it doesn't cause problems. It's as follows: The battery voltage measurement is very inaccurate, see the photo below. The device measures 7.3V and says OK whereas the real battery voltage of my almost depleted battery is 6.2V. This is a problem because the dropout voltage of the 7805 linear voltage stabilizer on the PCB is 2V. So while the device "thinks" that its supply from the 7805 is 5V it actually is only 6.2-2=4.2V which leads to some inaccurate measurements. So make sure you use fresh batteries. The 40 seconds auto shutdown helps conserve the battery. Apart from this I'm very satisfied with this product. Highly recommended.
