for what be be , it work well . bag will clog if cut wet material . bag lay on ground , so if ground be wet , it be a mess . there be no suction , so sawdust still come up from blade , therefore material will get sawdust on it , therefore sawdust will get on the ground . I do not know where to store this thing , so now when I need it , I be look all over the place for it . 2 1\/2 '' shop vac hose slide right onto saw . it be the better choice . I use a foot switch christmas tree extension cord so I can turn vacum on and off with ease .
