Lots of extras!
Size: 2+12+12+2 pack
The brushes are a bit flimsier than the original but otherwise fine. I needed it for the rectangular filters more than anything

EUFY 11S
Size: 2+8 pack
Used to replace the ones for my EUFY 11S vacuum. They fit just like the ones and got my vacuum back to cleaning really good. Didn’t realize how loud my vacuum had become until I replaced these parts.

Works great with Switch 2’s dock
I specifically bought this for the Nintendo Switch 2’s dock. I was worried about if it had the right amount of clearance to fit but it fits perfect!
Note though that only the usb 3 (blue one) one will work, the usb 2 one (black) plugs in flipped.

It's better buy both and to assure to get the right one and gamble into buying one and are buying it bc u got the wrong one. Works as intended
