I do multiple install in a day and any product that can save I time make I money . clean up be a requirement and I be hope this bag would at least help with contain the pile of sawdust that my bosch table create . it do not . in fact , the bag will catch about a 1\/3 or less and then because you have cover the exhaust hole , the sawdust will then blow back thru the blade opening into you face , even with the blade barely expose over you material . this blow back of course cause a dust cloud around the saw . its faster to clean up a large pile of sawdust on the ground from the exhaust hole than clean up a 5 ' area all around the saw from that dust cloud create by use the bag . it look nice and be big enough , but doesnt do the job at all .
