nice product for the price and is fairly accurate
Fairly accurate for hobby work. Nice price for its extended capabilities. The zeroing function is limited and under given instructions it is best to touch both test leads or clips when measuring and write down the reading for subtraction to the measurement of the component. The hold function does work, but I've never used it in component testing with a LCR meter, only on live circuits. Mine did not come with battery so be prepared to obtain a 9v battery. The plastic surround shell can be easily removed if it's bright color is annoying. All in all it has plenty of testing options and a zippered storage that most higher priced units don't have. The display can be set to various angles but does not lock until back in horizontal position.

Worth the purchase!
I've always wanted an LCR meter! It works amazing! Very quick readings, well within tolerance of known good capacitors, inductors and resisters tested. The only thing that would improve it, is a side pocket on the case to put the probes in when not in use. Minor, really, but a great meter!

A good value with a workaround.
Does a good job for the price. The insulated alligator clips are nearly useless because they can't attached to the probes. You can see inside that there isn't the usual socket that snaps onto the probe end. It's only the crimp for strain relief on the alligator clip is crushed flat to make contact with. All you can do is insert the probe and hope to make contact rather than attaching the probes so they can hang off a test point. The short probe for capacitance readings is decent but its leads carry too much capacitance to zero out. For small pF caps, I adjusted the probe capacitance to a nice number to make it easier to mentally subtract the value to get the actual reading. The values I read for parts were accurate enough to know if the capacitor under test was reasonably close to reading the indended value.

A speaker builder must have
Works as it should. Easy to use. Great for testing old parts to salvage. A speaker builder must!

Very good for the money
Very happy with this meter for the price. I verified the readings with some standards and it is very close. I wanted it because of the adjustable screen but found it worked so well for the price it is on my work bench now.

Excellent LCR meter
Works fantastic for both inductance and capacitance! I had fun checking every coil i could find, including of known inductance. Too many capacitors to check em all, but those tested were within spec.

Works Great
Works like a Charm, great value for testing Caps and Inductors.

Good tool if it works.
Good tool. Only concern is last one I bought in 2018 was dead in Aug 25 and in 7 years was not used very often. Properly stored, etc Hope this one last longer.

Prima toestel voor weinig geld
Het toestel is perfect voor de hobbyist die occasioneel spoelen of condensators wil meten. Ik heb het gebruikt om een reeks ringkern spoelen mee op te meten. De nauwkeurigheid heb ik aan de hand van een precisiefoliecondenstor bekeken, dat lag binnen de 2%. Best indrukwekkend voor zo'n goedkoop toestel. De afwerking van de plastic behuizing en rubber stootrand is wat je kan verwachten, maar het voelt toch stevig aan. Er zijn drie verschillnde snoeren/klemmen bijgeleverd, de snoeren zijn heel soepel en zien er degelijk uit. Ik heb het nog maar weinig gebruikt, maar heb eigenlijk geen negatieve punten ontdekt. Het enige wat ontbreekt is een handleiding die die naam waardig is, er is ook geen indicatie van de frekwentie bij de welke de impedanties worden gemeten.

Big nice display
Quite accurate and big display good for everyday usage.

Für Hobby-Elektroniker
Das LCR-Meter ist gut geeignet für Hobby-Elektroniker. Während das Ohmmeter und die Kapazitätsmessung ziemlich genau sind, muss man bei kleiner Induktivität Abstriche bei der Messgenauigkeit machen. Ich verwende es um BALUNs, Loop-Antennen und Bauteile zu vermessen. milli-Henry misst es recht genau, bei den einstelligen mikro-Henrys wird es recht ungenau. Bei Interesse einfach mal bei electronics unmessed reinschauen. Es ersetzt sicher ein Profi-Instrument nicht. Aber für den geringen Preis ist es eine klare Empfehlung.
