Goes well 3

For the rare occasions on which I would like to turn for example the expensive polarization filter to a smaller lens, it is sufficient.
However, for continuous use, the rings by the choice of not really high-quality material and the consequent probably somewhat crude processing are certainly not suitable.
Who at this price but expected a high level of quality will be disappointed naturally as justified.
Thus, should the "only" 3 stars do not be misunderstood.
Price / performance is probably 5 star.
