Pros : Seems to extract all the fumes as I cannot see or smell them anymore when I solder.
Cons : Without the arm (see below for other thoughts) this would have to be repositioned frequently on large panels to get the full benefit.
Other Thoughts : My review is based on having the absorber and the arm (which is a separate purchase.) I don't think it would work as well without it. With the arm I am able to position this over my panel. Without the arm, I would need to move the extractor around a lot to get it to work as well.
