im not sure if im using this right, but i may have messed up one of my pads. from what i understand you put the pc on a low speed setting and just hold the duospur still on the pad as it spins. i did that, but now my pads feel more rough as if the duospur kind of chopped away. i tried to catch it in a picture, but i was unsuccessful. has anyone experienced the same? and will i just have to toss this pad out? it just doesnt feel as smooth as my brand new white pad which has not been touched yet. after using the duospur the foam just became more rough.
