I needed a sprayer that would be able to shoot insecticide on to my two story house siding to prevent spiders.  I also needed it to be able to spray high into a tree.  This simple device does that well and more.  When you remove the deflector, it shoots a powerful stream a great distance.  With the deflector it produces a great spray pattern.  I have 3 other sprayers made by ortho, and by far this one is my favorite.  It looks simple, but it is very well designed and does exactly what I needed it to do.
