I have used swiffer products in the past, but never the Swiffer 360 Duster.
Here are my pros: I LOVE that the extended reach handle can go to places I might not be able to reach. That is the biggest asset, in my opinion. I love that this handle folds up for storage, and doesn't take up much space. I love that the Swiffer 360 picks up dust easily, and doesn't let it fling all over the place.
Here are my cons: I am not loving the fact that the Swiffer 360 seems to get really dirty fast and once it does, it won't pick up more dust, it just spreads it around. I also do not like how the plastic part of the wand that holds the Swiffer duster on pokes through to the other side. So, when I dust, the plastic always hits whatever surface I'm dusting. While that's fine for most things, if its delicate, like a lamp/light bulb, that's a problem.
Overall, I will continue to buy Swiffer 360 Dusters again. But I will say, without a doubt, that my favorite part of this kit was the long-handle. So simple, but it makes it worth every penny. (In fact, I already bought a second pack of Swiffer Dusters, so I guess I am officially addicted.)
