I bought it in November for 12 euros and with little use (no capacitor here and there) after 4 months it burned out. I didn't even press the button because it heats up relatively quickly. I do not recommend it...

Mediocre product, its resistance burned out within a year with minimal use.
If we compare it to a branded one that lasts for decades (or even forever), then it is expensive at 6 euros per year.
Not recommended, get a branded one.

A product that perfectly covers an amateur in electronics and soldering. I don't see the turbo button working, you simply plug it in and it operates at its own adjustable temperature. During operation, it is good to place the soldering iron on a metal object or a special base to avoid accidentally touching anything else and causing damage or harm. In my case, for example, I burned a fabric. For someone who knows what they need and considering the cost, it is a good choice. I do not recommend it for long-term or professional use.

Good as construction and quality but terrible in terms of reliability because after 15-20 uses and about 1 year, the resistor burned out even though I had never pressed the turbo button for more than the 30 seconds it says... But for the 6 euros I bought it for, it definitely paid off
