I somehow have missed this thread. Guys bought it a month ago and I can vouch for it. The cleaner cleans your car in a jiffy. Totally effortless and the icing on the cake- no scratches!!!. The handle is a bit fragile so be careful as not to exert too much pressure on it. Sometimes the long handle does touch the car body, but nothing to worry as its only plastic, with a little practice, you can clean the car without touching the handle to the body. Haven't used the interior cleaning duster, so can't comment.
Only draw back is, its sold in a combo pack. Delivery is damn fast, got it in 8 days flat.
