One of the tools that I mostly use, is hot glue gun.
It is very useful for me in many applications, especially when I want to mount alarm cables in wall corners.
I was own a STEINEL gluematic 3002 gun since 2003, which is still full functional although it has worked many many hours....
Unfortunately one day, it felt down from a ladder where I was on, and a small piece of plastic that holds its external housing, broke.
For first aid I use a copper wire to hold the housing of the gun, in order to finish my job.
But the time for replace it has come...
I had not have to think for other choices, because this model was excellent for me. So I bought the same model again for 20 Euros.
Also I bought an extra long nozzle for it ,which is very useful when you want to reach narrow areas.
