Works as intended
Works fine. Did what I needed it to do

10A current reading appears to be milliamp accurate
I was diagnosing a large parasitic draw in my car. My old multi-meter was either 200mA range with 1mA resolution or 10A with 10mA-ish resolution. This made trouble shooting difficult. This meter on the 10A setting appears to be at least close to milli-amp resolution, which in my case was super useful. The meter is easy to use and has a good display. Also, using AAA rather than the more traditional 9V battery is super handy. The meter is double fused with a couple of spare 600mA fuses in the package. Negative points are: * NCV detection range is very small. * Included leads (especially the alligator clips) are not the best quality.

Delighted with this test meter for every electronic measurement, great value, even has a backlight.
Absoluetly delighted with this test meter in every way, great value for so many features too. Lots of extras arrived with it, takes just 3 AAA batteries, supplied, and non of those messy 9 volt batteries that older test meters used to have. It covers every aspect of electronics measurements, and the LCD display even has an on off button for the backlight. Thank you for a truly impressive product. I have included some images too, and the meter even has a back stand too.

Great Device
I hate to say that in almost 40 yrs of repairing and building race and road bikes I’ve never owned a digital multimeter before…. I’ve always used a 1970’s Snap-On model that was originally my Dad’s, now it’s enjoying a well earned retirement and this one travels with me. Very highly recommended, good quality, accurate….. I’m sold on this one

Hard to see dial
Poor colors on dial make it difficult to choose correct setting. Fittings mostly okay but crocodile clip converters are awful leading to false readings. Had to make repairs to crocodile adapters. Probably should have returned it but I've stuck with it (or I'm stuck with it! ).

Good but slow
Just received the meter so haven’t fully tested it. Initial thought is that it is slow to display. One reason for buying this meter is that it came with croc/alligator clips. But I do not like the way they connect to the leads.

I'm Happy
Seems reasonable well made, as accurate as any other cheap meter I have owned, I'm happy with the purchase.

Für den Preis unschlagbar
Ein wirklich tolles Multimeter, dass für meine Zwecke ausreichend genau misst. Der Schalter rastet in den einzelnen Stellungen gut ein, die Haptik stimmt. Überrascht hat mich die Funktion zur (Strom-)Leitungssuche. Sie arbeitet zuverlässig und ist für den Hobby-Gebrauch absolut überzeugend. Beim Einstecken der Messleitungen beachten: nach den ersten Millimetern trifft man möglicherweise schon auf Widerstand. Der Grund ist, dass die Schutzummantelung aus weicherem, biegsamen Material gefertigt ist, dass nicht automatisch ganz gleichmäßig in die Buchse rutscht. Bei der ersten Anwendung dachte ich, das Gerät wäre defekt, bis ich dann festgestellt habe, dass man die Leitungen mit leichtem Druck und kleinen Drehbewegungen am ersten Widerstand vorbei manövrieren muss (geht ganz leicht, man muss es nur wissen), bis die Hülsen praktisch fast vollständig in der Buchse verschwunden sind und der abgewinkelte Stecker fast ans Gehäuse reicht. Ja, das klingt für den einen oder anderen trivial, aber vielleicht ist die Informationen für weniger geübte Hobby-Bastler dennoch hilfreich. :)

Works good
I bought this meter for my son and he loves it. We had to use it a few times already and it works great. Nice price also.

多機能で低価格なデジタルテスター
アナログテスターが使えなくなったので購入しました。トランジスタの導通テスト、抵抗値、コンデンサ容量測定、電圧値の測定に使いましたが、問題なく使えています。機能的には多機能で、低価格にもかかわらず良いと思います。 電池寿命や信頼性については未だ分かりません。

Ottimo tester, molto ben realizzato
Premetto che sono un elettricista. Mi serviva un nuovo tester da portarmi dietro dopo che quello precedente mi ha abbandonato dopo anni di servizio. Dopo un' accurata ricerca la scelta è ricaduta su questo modello principalmente per le dimensioni molto compatte e nello stesso tempo offre molte funzioni in più rispetto i semplici tester dei cinesi. Mi necessitava uno strumento che potesse misurare la corrente anche in alternata, ciò che molti tester economici non fanno. In più è autoportante. Non devi stare li a regolare manualmente la scala di misura. Ha anche altre numerose funzioni ma per un uso da elettricista non necessitano, mentre per un utilizzo professionale da laboratorio mi orienterei su modelli con funzioni ancora maggiori. Mi piace tutto di questo tester, è realizzato veramente bene; da l'idea di essere molto professionale. Ha persino la funzione NCV a mio avviso inutile, può servire per dare un' idea al volo se c'è tensione ma preferisco usare i puntali per verificare con più sicurezza prima di mettere le mani. Ho un po dei dubbi sulla reale lettura della tensione alternata ma non ho modo di verificare con altri strumenti. Gli unici due aspetti negativi: manca una borsetta per il trasporto e il display quando non è retroilluminato non si vede molto, i segmenti non sono molto marcati in nero nonostante pile nuove montate. Questo richiede spesso di attivare la retroilluminazione ma per il resto è fantastico. Nulla a che vedere con quelli che vendono i cinesi (e anche amazon). Non sto qui a dire tutte le fantastiche funzioni di questo oggetto, è tutto scritto nell'inserzione. Il bello è che è costato poco più di 18€!
