Good with potential for improvement.

So far everything is working satisfactorily. The Lee filters fit well, sitting for my taste but a little tight in the recordings. But they should not slip, too. A star deduction is available for use with 3 filters, which should be possible yes. In this case, the rear filter lies flat on the aluminum of the support and the slightly protruding out adapter ring. This can during insertion of the filter result in scratches. At the latest during the rotation of the holder to the camera to align the course of adapter ring rubs directly on the filter. For 5 star all filters should come only in the lateral guides in contact with the holder. Then nothing can scratch also.
