No problems with the vendor and delays in postage were with Australian customs. Tracking was good and gave confidence. The device itself seems a bit mediocre on quality. Lens side fits my lenses easily. Camera body side is a struggle. So far it does not fit on a K-3 body. It does (quite tightly) fit on my K-01 body, so I have the viable macro setup I was after. So, neither of these cameras are listed as supported, but Pentax quality suggests newer models should fit the same.
