Consistent with the idea that I was doing in the description and photo. Reliable on weight. Getting "tension" with short and little pronounced support (for another it was almost over and then climb back down for what positions to zero). Displayed weight quickly, sometimes hesitates between 2 to 100 g weight (not a criticism, here helps to see if it is up or down for next time) then stabilizes and re displays the weight permanently. Thin as described. The center is transparent else is clouded. Very nice on a tile him even in small tiles almost equivalent in size to those of the scenery because all restores the color of the tiles and gives the impression that it has this color.
