@DaneLaw: I also have problems with Aliexpress.
When I want to pay for “Choice” items in my shopping cart with Paypal, they are suddenly no longer “available”.
In addition, AE now charges in GBP instead of USD for Switzerland.
No idea what's going on, but I'll probably have to look elsewhere.

Good luck to everyone! I finally got the QP LINK LCR1S tonight. It looks like a good device. And the calibration complete board looks like a kind of dummy, since only resistors are soldered on it, there are no inductors and capacitors, there are only seats for them.

What's your impressions sofar, does the Tweezer also perform?

As speculated above, It does looks to be from the same "QP" vendor, that also makes the 3'button-white QPLCR, that is making the QPLINK when looking at stores, though the screen UI is also very similar.

Tons of sellers pop back up on Aliexpress.
from around 60$ and up (incl. danish EUVAT)

I bought it at the "House Improve Tool Store".
The tweezers for SMD parts turned out to be very good (for comparison, I also have Shannon ST42, FNIRSI LCR-ST1, HP-990C and some other devices), it is much better than FNIRSI LCR-ST1.
Measures the voltage (deviations from the source of the reference voltage are hundredths of a volt). At the same time, it also measures the internal resistance (ESR) of chemical power supplies, giving readings close to those shown, for example, YR1035+.
It measures both the capacitance of capacitors and inductance quite accurately, while showing Q-factor readings close to those of ST42.
This device has control modes for "left-handed" and "right-handed", it is configured in the menu (by long pressing the left button), there is an "Auto" mode (in which the image turns over depending on the position of the tweezers), there are also fixed positions.
In the "Menu" there is a choice of the type of equivalent connection - "serial" and "parallel". However, the connection type is not displayed on the display (as in, for example, ST 42).
The control of the tweezers is convenient, the purpose of the control buttons is easy to remember (there are no instructions included with the device, but as soon as I picked it up, I began to use it, as if it had been with me for more than one year). By the way, there is no charging cable (USB TYPE-C) included, we must also keep this in mind.

The back cover of the metal case is screwed with three screws (screw heads for a 6-terminal "star"). The probe tips are screwed with the same screws (2 pieces each). A screwdriver for these screws is included.
