Very satisfied with my purchase! The size is a bit small but it is absolutely not prevent good grip mills. The box is of high quality, pleasant to the touch (polished / sanded, so very soft). Paint and varnish applied seem to hold, we'll see over time. The mechanism is childish: simply unscrew, lift the lid, insert salt / pepper and screw. For large "grains", it takes very little screwed. Instead, to get a "sandy" appearance and fine, we must tighten. You can also view your screwing with the screw, above the lid. The mills are not exchangeable: the "pepper" mechanism is totally different mechanism "salt". In conclusion, very satisfied to finally have some nice pepper mills and salt. Difficult to find cheaper and more here. I recommend!
