The spreaders are very nice to look at, but you are limited by their function in use! For a dose not so easy, because you have to tilt very quickly to get not too much on the plate. If you do not keep the spreader vertically, the salt from sticking to the edge.
I also own the other two of WMF, these can regulate this a little better through the push of a button. Modern and nice but they are here. You have to know what you just need :)
