    Buon prodotto ma manca la perfezione nel contenitore
    A parte che non legge alcuni componenti come Thyristor e SCR, alcune resistenze e alcuni condensatori, ma sembra un buon prodotto, forse non molto completo. Un piccolo manuale soprattutto per interpretare le letture non avrebbe fatto male. Speravo dicesse anche il componente ma per esempio gli zener fa vedere solo un doppio diodo senza indicare la tensione di lavoro. Il contenitore e bello da vedere ma in realtà non è molto preciso. La parte superiore in plastica dalla parte del flat per il display non sono riuscito a montarla in quanto il flat e anche il display, bloccano l'inserimento dell'inserto. Ho dovuto limare il foro del pulsante in quanto avvitando le viti spingeva il pulsante blu contro la plastica trasparente. Ho dovuto limare un angolo della plastica in corrispondenza della leva in quanto andava a toccare. Di mia iniziativa ho messo tre viti che bloccano il porta batteria per evitare di muovere troppo il cavo rosso e nero quando cambio la batteria. Penso di avere trovato quello mal assemblato. Ma adesso funziona bene. Se avete un piccolo manuale per favore inviatemelo. Lo consiglio in quanto per la spesa irrisoria è utile.

    Did not work
    After an interminably long wait for the item to be shipped and delivered (45+ days) I assembled the items into the supplied clear plastic box only to find that nothing appeared on the screen when a battery was connected. I disassembled the components and tried various charged batteries to find that the screen lights up but displayed nothing.
    Thought about returning the item but considering the wait it took for the item to arrive I am UK and item was shipped from the Netherlands supposedly (obviously on the back of a snail) I decided to bin the lot and looked and purchased one from Amazon.
    I assume they do work according to the reviews but mine just didn't :(

    Having said that, it is the first item I have purchased from Gearbest that hasn't worked :(

    Working...
    (RO) Pachetul a venit destul de repede, circa 3 saptamani. A ajuns nevatamat. I-am construit carcasa (destul de usor si fara desen) si l-am pus in functiune. Spre surprinderea mea functioneaza perfect. Am testat mai multe componente...Functioneaza super. Recomand celor care au ca hobby electronica si au un mini-laborator acasa.
    (EN) The package came pretty fast, about 3 weeks. He got unhealthy. I built his case (pretty easy and without drawing) and put it into operation. My surprise works perfectly. I tested many components ... It works super. I recommend those who have an electronic hobby and have a mini-home lab.

    nice piece of equipment full of potential for further improvements
    This is an amazing piece of equipment for people with functioning hands and brain. It comes fully disassembled and it took 30 minutes, at least, to assemble it, as no instruction manuals were provided. But once assembled, it can surprise in functionality as gives quite accurate diagnostics on resistors, capacitors, diodes and transistors.

    I have one wish to the developers of the product. Please try to improve the product design so that replacement of the battery would not require to disassemble the whole box. Maybe some easy to lock-in removable battery cover?

    I'm happy, but there are flaws!
    I was happy with the purchase of the product and its work. But I had a problem with the assembling in the box. The display was not mounted in place on the board and it was in the box, pressing the ribbon cable. But with a little work from me, everything is fine now . Also add that it is good that the power cables from the battery box come out from the sides and not from below.

    Fantastic little device
    I bought two of these, one for me and one for my son. They both went together very quickly, with more time spent peeling protective backing off of the case sides than anything else. Both units worked without a hitch, and we will get plenty of use from them for future projects and education.

    To clear any confusion: All of the electronic components were already assembled. The DIY portion was assembling the case around the components.

    Nifty device
    Very handy device to have on your workbench! I tested a couple of transistors, capacitors and other parts I had lying around and it got the right answer every time. Also for a bi-directional two-color LED I tried by accident.

    I did have to put it together it myself (despite being advertised as "assembled") but that was fairly easy, once you realise where the cutouts have to be so the spring-operated parts holder can operate.

    LCR-T4 transistor tester
    PCB has splotches of flux and doesn't fit to its box. I almost damaged LCD flex cable because of that and had to remove one side near display. Bottom side has defects too (see photos).
    It doesn't detect thyristors but transistors pretty well.

    Nice device
    Gives instantly the necessary pameters for a transistor. But it is a little confusing with the socket and I miss a description in english (or norwegian) on how to connect the testing objects. I even saw a similar capacitor tester - this and other components, e.g. coils testing, could probably be included, making a really versatile device!

    Arrived damaged
    The display was cracked probably due to insufficient packaging.
    It was easy to assemble but obviously, with a cracked display it was not going to work properly.
    Your customer service is not properly set up to report aftersales complaints.
    I have ordered another but feel free to send me a replacement display.
