Good product from China and delivered in a few weeks! Complete with a box of very well made storage since the filter is absolutely not move inside, no visible color defects. One star less for the density scale is not very accurate, but for the price we will not s' to complain.
In short, an accessory that does what is asked for all photographers not wishing to invest tens of euros in a density filter. Not tested in the field, but for now I recommend!
