There's been a lot of web chat recently about this cheap Chinese device....
It's just a PCB with LCD display screen & a 'ZIF' socket, powered by a 9V battery.
It costs NZ$12-14 shipped (eBay/ AliExpress) + ~$3 if you want a clear acrylic case.
You can insert just about any common component into it (resistor, capacitor, inductor, diode, transistor...) & it tells you the ohms, farads, Henries value, cap ESR, the pin orientation, pin ID for transistors, etc.
It seems that maybe the accuracy of resistor, capacitance, inductance values may be only so-so (compared to a good multimeter), but the sheer 'plug & play' ease of use looks possibly handy - for quick basic ID of an unknown component.

Winner, winner, chicken dinner!
