Hard to believe that I have been using the WorkZone (Aldi) glue gun since October 2018, Check out my first post on it HERE. I have several hot glue guns in both mini and standard sizes and switch between them. I was working on a Depron servo box for my Jupiter Duck and suddenly noticed hot glue on my index finger, right hand. Sure enough there was glue leaking out. This was after it was sitting unused for several minutes. Maybe 20. So my advice with the Aldi gun is don’t let it sit unused for maybe 20 minutes. Use it, then turn it off until you need it again.
