Needs a better design. This applicator works, but takes a little experimenting and a little getting use to. I call it a puffer. You have to put several pebbles, ball bearings, etc., in with the powder to prevent it from caking. Then you need to shake it before each use, and most importantly, turn it upside down (spout/stem on top, and lid/plug on bottom) before you squeeze it. If the spout/stem is on the bottom, it will shoot out a heavy stream of powder. With the spout on top, and after shaking gently, squeeze the bellow gently, and see a small cloud of powder, indistinguishable from smoke, exit from the spout. That's all you need behind each switch and electrical cover plate. Also, sometime during the second year, the small plastic strip that holds the cap on the spout will probably break. Another reason this applicator needs a redesign.
