    5.0 out of 5 stars Work Well, Good Quality
    Reviewed in the United Kingdom on 4 June 2019
    Verified Purchase
    I dabble with electronics as a hobby and would be quite a heavy user of relays in my projects. I bought these after running out and compared with other ones I have bought from Amazon before these are very well made and are good quality.

    They work well and trigger exactly as they are meant to. Not really much else I can say about relays.

    So I can recommend them.

    Needed new relay for my doorbell circuit as the old relay burned out. Was pleasantly surprised that five arrived in the box, so great value for money. The picture showed a Songle relay but these have a different name on the top. Time will tell about longevity but they worked fine first time, so a happy customer here.

    Purchased to switch spindle on/off, on cnc router. Couldn't get to switch at first using 5v pin from arduino board and also tried 5v buck converter from psu (think it could be insufficient current). Tried 3.3v pin from arduino board and worked perfect.

    I bought these so that I could use a raspberry pi to turn on and off my my 3D printer. This works like a charm on the 24v power line for the printer.

    1.0 out of 5 stars 2 out of the 5 worked
    Reviewed in the United Kingdom on 30 January 2021
    Verified Purchase
    Very poor quality items when only 2 of the 5 I ordered worked. The first one worked thank goodness but when I set up the second system the relay wouldn't trip. I spent an hour going thorough the system, even tried another 2 relays out of the pack and still no joy. Eventually tested a relay block from another seller and it worked. tried the last relay in this pack and it worked also. Very frustrated.

    Uppfyller inte gällande isolationsavstånd med hög och låg spänning. Ska vara 5mm men är 0,7mm.
    Fullständigt livsfarliga att använd med 230VAC. Borde inte få säljas med de specifikationerna

    I was skeptical about products from China. But for the price, I gave it a try. Everything I ordered worked beautifully. China has enabled a world of opportunities, learners, entrepreneurs, educators, and inventors. Education would have been reserved for the riches without China. Thank you China.
