I orderded the Hammerhead brush, a curved adapter and a telescopting handle. The curved adapter will not fit into the brush. Apparantely from the illustrations on the package you need an extension that goes into the brush and the adapter snaps into it and the handle then snaps on to the curved adapter. I called Shurhold customer service about this and was told the part would be sent to me but it hasn,t arrived in over a week. Will have to send everything back if I donot receive this part which should have been sent with my order.
