Hello, I have bought this small device ($22 shipped): It is cute (wine red box, as stated on the box, I like that ;) ) and well thought: external 9-12V DC jack, test probes jacks, SMD socket, plug-in sockets, discharge resistor, ESR chart (on the back). The two buttons have the same function: for left & right handed :-DD. A few additional functions: The most useful is the "continuous" capacitance/ESR meter (C+ESR): no need to press the button for measurements. Even a decent "user manual" is provided: Don't turn it on, take it apart: Atmel MEGA328P, LM339 comparator, AMS1117 3.3V & HT7150-1 5V LDO regulators: Quick test: 330? resistor: 10mH inductor: SMD 1mH inductor: White LED: 470 uF capacitor: Transistors: Not impressed by a big power NMOS: No accuracy specification but measured values roughly agree with other instruments I have. Ideal for component identification. Michel. |

Quite a nice case variant of https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/ |

Hopefully didn't cost more than $20. :-DD |

I find it a quite neat interpretation of the original "Komponententester" by Karl-Heinz Kübbeler. I made one myself in the past: http://www.360customs.de/2013/12/transistortesterkomponententester-das-universalgenie/ Tooling yourself a nice (handheld) case isn't normally achieved at $20, so the price looks good to me. :box: Regards, doc |

I picked one up a couple months ago and have found it to be well executed and quite useful. |
