It took about two weeks and mainly catered for the 3D printing hobby. The 3D smoothing tip works perfectly, but the temperature of the soldering iron is not regulated and you have to act quickly or the plastic will melt. Used a soldering iron tip a few times (on plastic) and it no longer gets hot. To be honest I wasn't expecting much for the price, hence the 3 stars. Must check if and how to get additional tips (I doubt regular soldering iron tips will work with this).
