first , I do not have a dust collection system , but do have a shop vac and the Bosch dust bag be still the 2nd best of my 3 option , and probably the best option for the money period . the bag have a pretty good capacity , and in itself do not seem to cause any clog in the saw 's exhaust port that would not naturally occur . it clamp securly to the port and its simple to use . I preffer it over hook up my shop vac because it do not draw any more power , be super easy to hook up , and be easier than trip over my shop vac that always get in the way . this do a very good job at collect dust and I would definitely recomend it to anyone not use a collection system .
