Fast delivery, good packaging. Excellent product! Everything turns on and works. I haven't yet figured out the device itself, but I will study it. From the packaging to the device itself, it's clear that they tried to make everything very high quality. I recommend the product and the seller!!

good quality

Item works very well, as advertised. i detected high radiation in some old airplane instruments
C
everything as described

It seems to be working. Unfortunately, there is nothing radioactive to test. The RadPro 3.1.1 firmware feels like home, and the functionality has become more advanced. The build quality is okay; the tube is intact, the microchips are worn out (as is usual with Chinese products). I hope I won't need it, but with such neighbors... it's better to be prepared.
K
Superb interface, very clear readability, choice between different types of measurements, including Sv/h.
works very well.
D
excellent shipping. highly protected.
It is the version with the original M4011 (J321) tube manufactured in January 2026.
It works perfectly and has a menu in several languages, including Spanish. I will proceed to install the new firmware and provide an update.

Solid quality, does the job nicely.

Perfect! device have m4011 tube and mcu is apm32f103rbt6. newest radpro funkctionaly correct!

Genuine gc-01 as expected from the official store.
Came in a thick polystyrene outer box so was totally protected, very impresed with the packing.
Works great, will try radpro later once i get time but works fine out of the box with the normal firmware.
Has 4011 tube in it.
K
Super nice
L
It looks very well packaged.
The internal assembly of the device is also not bad, although the battery is too small at 1100 mAh; it's good that it's detachable - there's a possibility to increase it.
I will try to install custom firmware from GitHub.

Seems to be the real deal, excellent.

Everything is great!

The device is a bit smaller than I imagined, but that's actually a good thing! It's wonderfully compact and you can carry it in your pocket. The shipping was reasonably fast. It works for my periodic table collection of elements. It also continuously measures background radiation. It does exactly what it promises. Great brand with excellent products!

Great! Everything is great! The seller is top-notch! Everything matches! Sensitivity to weak radiation is good! I am satisfied!
Excellent! Everything is great! The seller is top-notch! Everything matches the description! Sensitivity to low-level radiation is good! I'm happy!

Item's charging circuit is shorted internally

It did come with the m4011 tube as promised and i was able to flash it with radpro, although only the 2.1.1 version as the 3.x branch currently has an issue. But overall i'm very happy with it.
