I guess Swiffer is getting rid of the yellow 360 dusters and the blue dusters and replacing them with these. They are made like the blue dusters with a little bit of fuzz between "fingers" of white Swiffer sheets, only there are 2 of them glued back to back, so they go in a full circle around the stick and are yellow instead of blue. They are not really at all like the softer, fuzzier yellow 360 that people are used to. To me, the new 360 and the old 360 dust about the same, and I don't mind the change, but I always did prefer the texture of the blue ones over the yellow ones, though I did prefer the full circle of the yellow ones over the blue ones.
If you like the original 360, I suggest you stock up, because, as I said, I think they are being replaced by these.
To me, these are good for a quick dust, but I will still use them in conjunction with the Swiffer cloths, and even just a damp rag.
