    I did not receive the product in the pictures. The product I recieved does not have the wifi and bluetooth stickers as the one in the pictures. The materials feel like the cheapest possible plastic and soldering for the battery is "sloppy". It also does not work as expected, when I uploaded the device info example sketch from the arduino ide, I get an error stating "Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled. Overall, I am not happy with this purchase.

    Трекинг отслеживается только через Китайский сайт, ссылку получил, запросив через приложение Banggood. Внутри Москвы доставка через CDEK до ближайшего отделения самовывозом. Качество сборки нормальное. Проверять буду позже.

    Nice as expected. For first test, apply battery, press PwR button for a longer period and put device aside until the red GPS/PPS LED starts to flash (then it got a satellite fix). My unit hadn't any sketch loaded as another version before so you have to do further steps to get it operable. Recommended!

    Reasonably good, there is no clear description on what version these were when I ordered them. Once I started coding for them I realized it is key to know this.

    Received the V1.0 model which had a different power management chip that’s I2C controllable. got mine working as a The Things Network mapper currently until I get around to writing my own software for my project. Will likely be looking at purchasing more in future.

    It is a very interesting product. Quite expensive compared with other sources. I haven't yet run extensive tests but it looks good. Packaging was quite essential but product was delivered in good shape.

    Works like a charm. Used on the TTN network, range is not bad. I did buy An oled to go with this later as option.

    Arrived on time, and in good condition. Works as described, and all parts & instructions were in package.
