I have changed my quick release system based on a Manfrotto Kopfesvon Cillmann to Manfrotto. This plate, I now use on my monopod. The safety lever for the locking lever I find extremely inconvenient and rather poorly resolved. Honestly, I was looking back to Cullmannverschluss even much better, only the magnesium ball head leaves me no choice, unfortunately. Overall, I prefer from and a 1 1/2 points for the closure. Half point for the price - I find it then too high. In addition, I would want from Manfrotto labeling to which disks which couplings fit securely. Perhaps there is indeed, but as a trained that ought to be somehow recognizable.
