The accuracy specifications correspond to the price....
I would rather save up for an ST42 from Shannon, then you would have won several times over.
For example, as far as support is concerned, you can completely forget that with "Fnirsi".

This product is almost similar to the same one from ZOYI ZT-MD1.

It seems that Chinese friends will soon fill the market with devices that will compete with the famous MASTECH MS8911 ;)

I would've also paid several times over. That's a device in a completely different price class.

I know, hence me asking if anybody has tried these. Never know with FNIRSI if the firmware actually works. The Miniware tweezers seemed interested but they also seem to have software problems.

Yeah, could be a re-brand. Can't find the ZOYI ZT-MD1 for sale on AE, no reviews anywhere either.

I can only find the MASTECH MS8910 for sale and that seems like a rather basic DMM, none of the LCR features.

And completely different capability class.

After nearly 2 decades of using SMD LCR tweezers I can vouch ST42 are currently incomparable for their cost.
