Unpacked the set seemed quite ok. The cable of the soldering iron is sufficiently long. Only the holder is a little wobbly.
The first time you use the soldering iron and solder for the supplied LED Stripes had to serve. But with a bit of tact and a steady hand also with this soldering iron is loose feasible.
To Lötpumpe I can not say anything because I have not used.
For the price a good performance, so strong buy recommendation.
