On full power it still does not pull all the smoke in even if I put it directly next to what I am soldering. It’s a brand new unit with brand new filters. After I purchased it reviews mention not attaching the hose extension and keeping the hose as straight as possible. But that defeats the purpose. I would skip this and spend a little bit more money to get more power/a better unit. It is sturdy and comes with extra pre-filters which are a plus. But doesn’t work great imo.
