I be apprehensive about this collection bag base on the review . however , for the price , and because I be generate a lot of saw dust , I decide to give it a try . I do have a rather powerful shop vacuum that I would sometimes attach to the saw for larger job , but that be always a hassle , and particularly for those occasional short cut . so , I decide to try this dust bag . to my pleasant surprise , it have work very well . apparently , Bosch have make some improvement since other review be write , since the bag I receive be make of heavy cloth material and have a nice zipper in the bottom for easy saw dust removal . the bag collect virtually all the saw dust that go through the dust port , and only when the neck of the bag get inadvertently restrict by the power cord do it ever clog up . on the occasion when I have attach the shop vacuum , I really have to say that I do not think it collect much more see dust than this simple -lrb- and inexpensive -rrb- dust bag do . so -- bottom line , the dust bag seem to have be redesign by Bosch , and for I it work well , and much better than expect . for the price , I do not think you can go wrong .
