This kit arrived today. I had to throw away my old brush and filter because they just wore out. I DEEP CLEANED the unit and then reassembled it with the new filter and brush from this kit. I ran the vacuum cleaner 3 times because my floor was very dirty. The unit worked the same as with OEM parts and I had to empty the bin twice. The filter collected a lot of dust and the brush looked like felt and ALSO seemed to work like the original. I can't say anything bad about the price. The clip made a crackling noise on the filter when first pressed but it didn't come loose like others said and the second time it flexed more easily and came out instantly. So if you have a D5 hooked up I recommend this kit as a cheaper alternative to the same from NEATO but more than double the price.
