The product is fine for its price. It heats well and very quickly. For those who have an issue, tighten the screws that hold the tip very much, even if they seem "tight." When the tip gets old, it needs to be replaced and this is the disadvantage: I don't know which tips can be used as replacements and it requires improvisation.

the worst soldering iron I have ever bought! It doesn't heat the tip enough to melt the solder, its temperature drops for no reason, the transformer gets scorching hot and the tip doesn't! Wasted money...

At first it was fast. I have had it for 2 years without frequent use and now it is slow like a soldering iron pencil and it annoys me

Heats up instantly. Easy to use.

Awesome, it immediately reaches the temperature for soldering in 2 seconds, it also has a LED light that illuminates where you are soldering, the construction seems very good, it does not have temperature adjustment as it says, but this is not a problem, if you want to solder something more sensitive you just press warm up and immediately let go. The plastic case is very convenient, of course, don't expect something better, but you have everything organized inside. For the price it has, it is excellent.
