    Go unlucky and received a unit from a lower quality batch. No support for the ICs, missing resistor meaning the power LED does not work, badly connected resistor, and even an inductance mounted SMD style because the leads were cut too short. The solder joints have not been heated enough and the solder did not penetrate in the vias. The board is pretty dirty (flux and solder residues that could short tracks). Otherwise, the device works and is quite cheap. It comes with a lot of accessories which is useful.

    Cheaper geiger counter This is a good geiger counter at cheaper price, perfect to connect with a ESP or arduino module to make a portable radioactivity meter. The board show the particle detected via a buzzer a red led and via TTL pulse output. The module can be connected to battery pack (primary or NI-Mh cell) or directly powered from an Arduino or ESP module via 5V pin. Useful to continuos meter the enviromental radioactivity. A good Geiger counter +++

    I was very surprised about the high quality of the packaging. The module works immediately very well and sometimes detects cosmic rays. I tested it with a source of Americium 41( who is inside of a old radioactive smoke detector ). I recommend this module, good quality for the price. Thank you Bangood. Sorry for my poor english language, i'm french.

    Товар соответствует описанию. На момент покупки самая выгодная цена. Спасибо продавцу за упаковку трубка счетчика пришла не разбита (самое главное в этом устройстве). Качество пайки не на высшем уровне (видимо на плату попали капли припоя - возможно это частный случай, к счастью без замыканий), что не повлияло на работоспособность. После подключения заработало сразу баз проблем, индикатор мигает, звуковой сигнал присутствует.

    The Geiger counter arrived after two weeks in UK with the tube safely packed in a piece of plastic pipe. The PCB can accommodate tubes of 2 lengths. Unfortunately the shipped tube is shorter than the smallest position and it is not firmly hold in position. What I did was de-solder one holder, drill another hole in the PCB and then re-solder the holder. This has shortened the gap with 8mm and now to tube is hold properly in place. I've purchased a thorium gas lantern mantle (from old stock) and verified that the counter works. The tube is not the most sensitive but can be replaced if needed. The anode voltage is around 400V. Before and after the mod pictures are attached.

    Excelent product, arrived in a fairly good time, was extremely well packaged, with lots of foam and with a special case for the glass tube, and everything worked perfectly. All accessories are a great plus, and the Geiger Counter itself (circuits and tube) is the best product that I have found available for this price. I absolutely recommend it.

    Hooked this up to an ESP32 using the Pulse pin and wrote a very simple counter / dosimeter program for it. Really impressed, accuracy seems spot on also.

    Recibido hoy (pedido el 10/10). Envío un poco lento, pero ha llegado en perfectas condiciones. Muy bien protegido, doble caja de cartón y tejido acolchado. Lleva un protector de plástico para proteger el circuito y el tubo. Este protector es muy sencillo de instalar (recuerden retirar el film protector que lleva para que no se vea opaco). Los cables y el portabatería de buena calidad. Circuito con buenas soldaduras y bien terminado. Probado, a falta de conectar a Arduino, funciona a la perfección. No lleva ningún tipo de manual, pero la información que facilita el fabricante en la página del producto es más que suficiente. Comunicación con el vendedor profesional, atenta y rápida. Muy recomendado! En definitiva EXCELENTE!

    This arrived extremely well packed, with some minor assembly needed (tube and top cover)... initially it made a hell of a screech when turned on, but a bit of emery rubbed on the GM tube contacts and the test jumper removed fixed the issue. I've always wanted a Geiger Counter, and love it!!!! I plan to connect it in with the GPS receiver, mini display and store the values to an sd card in CSV format.

    It was very well packed. The tube is a little shorter, so it has to be put on carefully and it works. I have one more tube and it is longer than the connectors on the board. Life is sometimes quite complicated :-) The device works, I tried it on an old CRT TV. It was necessary to attach the tube directly to the screen and then it beeped quite quickly. I can't verify accuracy and sensitivity, so I have it as a fun toy.
