    The product is very innovative, as well as very compact device. It is working perfectly. Only detail operation manual was not enclosed with the product. we have to learn the detail testing procedure. so please provide the link for take help. Another help is required the procedure for pairing with PC and android. Thanks Banggood.

    Oggetto e arrivato in ottime condizione ero titubante. Ancora lo sto testando ma sembra che faccia proprio quello riportato nell'annuncio. L'unico problema riscontrato e quello della scheda bluetooth che e stata posizionata in una zona non proprio ottimale con facilità di rottura. Nei prossimi giorni finirò il test

    A encomenda chegou um semana antes do previsto. Excelente produto bastante útil e pratico. Não veio com nenhuma caixa ou manual. Vei sem qualquer indicação de qual a APP a instalar no Smartphone.

    I use it in the test of the LiPo battery. We take data in PC and graph it with EXCEL.

    I bought the bluetooth version so I could wire it into my WiFi router power cable and measure its consumption. Works well at 12 volts. The Bluetooth app is available on the Play store as UM Meter. and it shows up as JDY-30 for me. I haven't compared the results with a digital voltmeter , but they are what I expect. I took off a star for Appearance as there is no cover for the Bluetooth dongle.
