The seller is nice. I recommend it!
Shipped very quickly.
The package arrived in Kyiv via Ukrposhta.
And it also arrived as quickly as possible: it was supposed to arrive in the “corridor” between February 2-7, 2026.
And it arrived on February 2, 2026.
The box was very nicely and carefully packed.
It arrived completely UNDAMAGED, as if I had bought it in a store! The box was with the film maker.
The USB tester itself is of good quality, original!
I ordered the Bluetooth version:
Fnirsi FNB58 + Bluetooth.
And that’s exactly what I received.
It differs from the version WITHOUT Bluetooth in color: blue-gray. And the BlueTooth icon on the “label” that goes on the “back” of the tester. There is neither the word “BlueTooth” nor the corresponding icon on the front side of the tester. And on the yellow “cloak” it is simply written:
FNB58
But don’t be afraid — this is the Bluetooth version. Moreover, the version WITHOUT Bluetooth also differs in COLOR: it is BLACK. And this one is blue-gray.
Satisfied with the purchase.
The quality of the tester is very good!
Thank you to the Seller for the great product!
And to you, for your attention!

An excellent tester. It allows you to check many chargers and cables. It is advisable to read the instructions before use. This ensures full functionality. For some reason, I have a problem where the tester cannot identify the chip in a 100W cable.

The box arrived in a clean condition without any damage. When I slid the box open, there were two certificates of conformity included with the main unit for some reason. There was no instruction manual. I used it a few times, and everything seemed to work normally, including the buttons. However, even when I turned the G-sensor off, it was not saved, and when I restarted it, it was back on. The firmware was (V1.11). I think it’s a good product. It’s fun to use, thank you.
