Excellent service and quality

Excellent service and quality. Blows my mind that this can ship so fast from a country at war and is cheaper than the Chinese copies. Really nicely put together. The web support is great and the home assistant took 5 minutes to setup.

Great counter for a decent price

Great counter for a decent price. Works seamlessly with a wemos D1 to integrate in my home assistant!

Thank you for choosing our product and for your high rating.
Regarding unexpected additional customs clearance costs in the EU: unfortunately, our company is not a resident of the EU or the Eurozone. Therefore, we cannot act as a tax agent and withhold taxes on behalf of European government agencies when paying for goods on our website. However, we warn our valued users and customers about this: see the section Order processing and delivery policies:
https://iot-devices.com.ua/en/estimated-delivery-terms/
As an alternative for future purchases, we recommend that you consider ordering through our Etsy store. In this case, all taxes and currencies will be taken into account immediately when paying for the order.
Ukrainian law also requires us to accept payment exclusively in the national currency. That is why we show the approximate price in US dollars, so that you can at least get an idea of the price level for comparison.

Sincerely,
Oleksii

Best DIY Geiger Counter with awesome documentation and support

I have been running two Greg20_V3 geiger counters modules from IoT-devices since two years.
I bought two more of these modules recently.
These DIY Geiger modules are great and easy to interface with an ESP32 microcontroler.
International delivery is surprisingly working well from Kyiv (Ukraine), even though a little slow of course.
Customer service is outstanding.
Support Ukraine!

Thank you for your feedback! We believe that every review adds important information about products and their manufacturers to the community. We appreciate your help in providing an evaluation of our DIY Geiger counter module that you purchased from our website.
We would also like to add that GGreg20_V3 has found its users in at least 27 countries. We do our best to continue to deliver orders from Ukraine, where our products were designed and continue to be manufactured. Despite the aggressive and unprovoked war against Ukraine, Ukrainian companies and organizations are finding innovative and unconventional ways to continue doing business.
Thank you for your support of Ukraine. We feel it and appreciate it.

Sincerely yours
Team of IoT-devices, LLC
