The fleece material is strong and I’ve never had one burst despite heavy duty workshop and DIY building use.
Seem to be slightly different design from previous bags. Remains to be seen if they are as good. Non genuine bags usually split.
Seems to hold fine dust well. My filter is still nice and clean.
Work very well with no dust exhausted
Good size, does the job, affordable
Don't buy these to fit a nilfisk 26-21 vacuum as they don't fit.
