Unfortunately not fit 100%

In addition to the price which I think is sher covered, I'm not satisfied with the fit of the removable disk.
Have the Slik tripod including ball head and removable disk and a second ball head with removable disk and still needed an extra removable disk -So I this ordered here.

Unfortunately, the panel does not sit 100% fixed in the bracket of the head, but did play in height, so that the image as you release the camera shifts slightly downward. Can I live with, but I do not actually, certainly not for the money, which is why only two stars.

To price ratio: the kompl.Stativ with head + plate has cost almost 90 euros and here the exchange plate alone nearly 18 euros -The I think too much.
