I broke my old sprayer which was my fault so I came hear to buy another one. I must have had older model (orange accents instead of yellow) because the new one that I got has a different dial and it is way more complicated to use then the previous version. Old version was set the ounces per gallon and start spraying. The new model is not as easy and and make you set the dial based on how many finished gallons of product you want to spray. Then run some calculations before filling container.
Seems to be of solid construction however the removable down tube wouldn't stay connected to the top of the apparatus. It is made to be removable but, it seems to me that it should stay on when you want it to. I had to glue the tube on in order to make it stay on, thus losing the ability to use it as a dry sprayer, but now, at least I can use it as a wet sprayer.
Do yourself a favor and glue the pickup straw into the top before using. Yes, this will delete the granule option but, you won't be stopping every few minutes to open the bottle, reinsert the straw, then make your best guess as to where the chemical stopped spreading. Gluing the straw first will cut your work time in half.
