Good soldering iron and the build quality seems good, I have to say that I was impressed by the quality of the cable, which is something like rubber and has no memory effect and does not retain kinks from folding it back into the box. Now, the reason I deducted one star from the rating, when I had the opportunity to purchase it, I decided to test the temperature sensor with my multimeter that I had never used before. In the first photo, I have the measurement of a simple Chinese soldering iron (6 euros) that I have had for 10 years with simple amateur use and it showed 250 to 260 degrees Celsius, which is perfectly normal for a simple soldering iron. In the tests of the new one, I saw that on the first scale (280 degrees), it reached 180 and on the last one (480 degrees), it reached 370 to 380, as shown in the photo, so roughly it is about 100 degrees below each indication. If you know this, it's not such a problem as long as you set it to 330 or 380 (meaning 230 to 280 degrees Celsius) for a simple soldering and 480 for something stronger. I believe that the first scale is not useful since usually solders melt at 170 to 180 degrees, so it will be borderline. But even so, if it lasts as long as the cheap one, it will be perfect.
Edit
In the end, with my first soldering, I confirmed my previous numbers as on the first and second scale, the solder would barely melt and gave me a hard time, from the third one onwards, everything was okay. Maybe it's just an issue with mine because I didn't see similar comments from others, but even so, everything is fine from the third scale and above.
