  If you can't find it as "Victor," it comes under various names but it's the same.

  Very small and convenient for storage because it carries its probes in a box that closes and everything is together, it doesn't need another case. These probes are its *advantage* and **disadvantage** at the same time. To put them inside, you fold them in a strange way and they break/cut at the points where they "fold." And if (when) they break, they are not replaceable with others from the market (there are no "holes" to put new ones). You need a patent to put new ones (unscrewing or "joining" on the old cables) and in the end, it won't carry them and the lid will close (so it's not that small anymore).

  In general, the plug-in probes are not convenient if you use them frequently, but that's why it's very portable. Mine got cut at the top end with one probe from constant bending to fit into the case. In the end, I had to come up with a solution to connect it again (with cutting, soldering, tape), and now it's difficult to insert the probes and they will break again if I apply pressure because the height of their case is just right. I now leave them outside, but now I probably have to remove the lid because it's annoying since it doesn't close.

  Otherwise, it is "automatic" (you don't set the scale, but if you want, it also has a manual mode). Although it's not very fast in finding the scale and settling at the correct value, you can't say it's too slow (okay, slower than other more expensive ones that are faster). Its accuracy is VERY good, even compared to much more expensive ones, although over time it may lose a bit. You can see reviews on YouTube.

  After years of use (occasional, of course), the rotary switch sometimes makes contact and sometimes doesn't in certain positions. For example, you put it in the first position, which is DC voltage, and it does something "strange," it shows a measurement of C (temperature) which officially it doesn't have (like a hidden position). Of course, it doesn't measure temperature since it doesn't have a cable with resistance, but if you put something on the electrodes, it might measure. The same goes for Ohms, where it shows A (current) measurement (which officially it doesn't have). I didn't try it. Obviously, the circuit board has additional functions that haven't been officially disclosed, and due to poor contact, they appear. Other larger VC models do the same (have hidden functions) and there are "hacks" on YouTube to exploit them. On the back of the board, above the batteries, there are 2 "buttons" (on the board, there are no buttons), one says hold and one says select. See a photo of the back with the lid open. If you touch it with something metallic (as if you pressed a button if there was one there), the hold function works (freezes the measurements and shows the current reading, for example, in volts). All this while there is no hold button in the front. I didn't investigate further about the select button.

  It requires 2 AAA batteries and it turns off by itself if you forget.

  P.S. It doesn't measure amps (current), which is okay since it's not frequently used as a function by most people and it's also "dangerous" (to burn the Polymer, to melt the probes, etc.). Of course, if you want that, look elsewhere, I just mention it in case you didn't notice. Although it does measure capacitors, it doesn't measure very large capacitors (4 nF to 200 uF)
