I have been trying the Swiffer 360 duster starter kit  for the past three weeks and have enjoyed the convenience of the ability of reaching dusty places in higher locations. Having a bad knee and not being able to use a stool to have to reach is definitely a safety issue and the Swiffer extender has made it quite helpful.  I was impressed at how easy the dust extender was to put together. The 360° extensions make it great to reach those challenging places and the 360° duster does a good job collecting the dust & dirt.  I gave it 4 out of 5 stars because I wish it held more dust. I dust then have to shake off what was collected and resume again, several times. Overall this has been a pretty  convenient duster to use.
