The workmanship is very good, as was the service. As a drawback, there is the problem that the plates do not have laser treatment, would wherever you find through the zero point. This is important so that the camera always sits in the same postion in Panofotografie, as an old hobbyist I have created its own solution. In other plates I had minor problems, so that these fit not as great as the Sirui products. Price / performance strong buy recommendation. Sorry, missing only Kameraspezische plates by the manufacturer, this one would need then also not ausrichten.Ein problem I have less, camera, tripod, Panokopf are changed in no time without the need to be afraid to drop the camera out of his hand.
