At the end of the day it's a dust bag and it there isn't much you can go wrong with. The bags have a cover which stops dust from getting out when taken out of the station which does the job adequately and the bag itself seems strong enough to not rupture accidently. It seems however that the bag is divided into two sections in the middle and it seems that only half of it gets filled up which I'm not sure if it's intentional but feels like wasted space.
